Upgrading From A GT640 (ddr3 vs. ddr5)

Hey guys! This is my first time coming here to the forums! I made this account awhile ago for a giveaway, (like so many others) though I have been a long time fan of Linus on youtube :P

The point I'm making here is I go by ffxiimaniac now, I just don't know how to change it on here, or if you can. Though that's not the point of this forum post now is it?
 

The question at hand: I'm looking to upgrade my rig from a GT640 (4GB - DDR3) to a card of equal value. (Okay just a bit more expensive)

 

Since I currently am not getting enough FPS to my liking at 1080p :( ~20fps~ 1080, ~45fps~ 720P

(Both benchmarked in Just Cause 2 with the settings turned all the way down. (resolution aside)

 

The goal here is to upgrade my card to a better graphics card around ~160$~ give or take.

 

I'm having trouble seeing if the purchase is worth it, and if it is, what you guys/girls would suggest?

 

My daily usage is just the occasional gaming at 1080P with only one monitor, and then using my two monitors for normal activities. (web browsing, etc) I also run and would like to record PCSX2 1080P 60fps the best. With my current card I can do this, but with significant frame drops :( ~goes from 60fps to 4fps and back to 60fps every 5 minutes of recording~ I'd like to remove this issue by improving my graphics card to GDDR5.

 

These are not emulator glitches, as JC2 and other games do it as well. I'm guessing the DDR3 can run it at 1080P, but it can't keep up! (hence the drops) 1GB of DDR5 seems rather small, and that is my question to you. Is it really that much of a difference to go from ddr3 to ddr5 even with the loss in GBs? & if so, which graphics card should I get?

 

As for what I'm going to do with the old card well... I'm looking to sell it! (assuming I get the new card) So if you're interested let me know........ I'm thinking ~90$ *USA Only*

 
My current Card: (Mine Has A Cover Over It For Some Reason)
 

Here is the card I'm looking at buying:

 

GTX750TX

Here's the specs I have (as a reference)

Specs:

Thanks for reading this post :D Hopefully you can answer my questions. If this is in the wrong forum please excuse me!

You should be able to get an R9 270 for $160. That card can pretty much max games at 1080p and get playable frame rates.

Thanks for the info guys. Isn't Nvidia better/more stable though? I only went AMD for the CPU because it was cheaper. (I had a strict budget at the time) EDIT: I can't do that card unless you guys think it's really worth it. It says it needs a 500Watt psu.

You could get a GTX 750 Ti with 2 GB GDDR5 VRAM for 140$ with 20$ rebate: http://www.newegg.com/Product/Product.aspx?Item=N82E16814121855&cm_re=gtx_750_ti-_-14-121-855-_-Product

 

I guess I can't do anything anytime soon yet guys. I don't have 100$ to spend on a PSU since I only have 450Watts. (those cards seem to require 500watts)

Would you consider a used R9 270 or maybe a radeon 7950 or so?

 

You can run a 270 non-X without problems on 90% of 450W PSUs as long as it has a single 6 pin connection :)

It does have 6 pin connections :P (one) Though I have 2 Hdds would that still be enough?

Yep it will be:)

 

R9 270 is a very good choice for you. If it's a bit too expensive they go cheap used online. :)

This?

And if so, is it worth losing 2Gb for going from DDR3 to DDR5?

Yep. Speed is much more important than quantity for graphics cards at this tier.

What's the difference going to be like for 1080p recording? :P (fraps)

Between GT640 and R9 270 it's going to be a world of difference.

 

 

Really? D: That's bad that I spent 145$ on the GT640 because I didn't know the difference :/ I wish I could find somewhere to get a decent return on it, but I'm guessing I'll only get 100$ back..

Aww $140 :(

 

Yea generally speaking the lowest you want to go for gaming today is:

  • 2GB of DDR5
  • 750ti for nVidia
  • r7 260x for AMD

Anything else is inherently bad value for the money.

I knew better then to spend 100$ on a 1gb ddr3 lol. That's why I made sure I had more Ram. Seems it didn't matter lol. Also that video you linked me says it takes a 500watt psu?

They tend to recommend more than it needs just to be safe in case people use really crappy PSUs.

 

Your PSU should be just fine. My brother has an FX8320 + R9 270 on a CX430W PSU without any explosions or house fires.

I'm not worried about explosions haha. If it's not enough, it just wont turn on. My worries are I have to sell my old one to get the new one. Which if i do that and it's not enough power D: :( Also any overclocking advice for that card?

My advice would be to drag the sliders to the end and have a field day :P

 

That's what most people with R9 270s are doing including Slick in his review.

I've never done it before so I'd have to be sure on what I'm doing before I did it lol

It's pretty safe and not too dificult. You'd be hard pressed to break something when overclocking as the software and your motherboard bios(cpu overclocking) will tell you and sometimes refuse to boot and reset themselves if you're running at dangerous voltages. (Which was annoying when I was chasing 5.3ghz on my i7  :()

no worries we can guide you once you get the 270

Budget? Uses? Currency? Location? Operating System? Peripherals? Monitor? Use PCPartPicker wherever possible. 

Quote whom you're replying to, and set option to follow your topics. Or Else we can't see your reply.

The GTX 750 Ti onl y requires a power supply of 300 Watts

 

The R9 270 seems to be a much more powerful card, so I'll stick with that. (assuming I can) Also since I already have AMD well...

Just to clear things up a bit....OP it seems that you are believing fast RAM = better performance GPU. Not necessarily.

 

A GT 640 with...6GB of GDDR5 RAM will never outperform a GTX 780 with 3GB of GDDR5 RAM. Even if they some how rigged up a GTX 780 with GDDR3 RAM, the GTX 780 will still trample on the GT 640.

The VRAM found on graphics cards essentially functions as a temporary storage location, a buffer if you will, for all the data that the card needs to process before it is sent to you monitor / display for viewing.

 

You need to take account the other components and aspects that make up the graphics card, like:

  • The GPU chip used (the brain and heart of the graphics card)
  • The frequency (speed) of the Core, Shaders, VRAM, etc.
  • The memory interface (128-bit / 256-bit / 384-bit / 512-bit, etc)

The type of VRAM and the amount is only a small part of it.

 

A GTX 650 with 4GB of GDDR5 http://www.newegg.com/Product/Product.aspx?Item=N82E16814125509

Compared to a R9-290X with 4GB of GDDR5 http://www.newegg.com/Product/Product.aspx?Item=N82E16814202110&cm_re=R9-290X-_-14-202-110-_-Product

The R9-290X is easily 3x - 4x faster!!

 

An analogy would be...comparing two cars by the number of seats it has.

A 7-seater mini-van will lose to a 4-seater Subaru WRX STi or 2-seater Porche 911 GT3 in a race.
