GPU HELP! :(

[saltandpeppin]

Hi guys n' gals, i'm in need of some help/advice!

 

I'm looking to upgrade my pc, I had purchased a pre-built gaming pc (which was okay at the time) and is now extremely dated. I'm in need of new parts.

 

let me give you my specs before I go any further.

 

(not 100% sure on the brands of all parts)
2TB HDD (Seagate) 
16GB Ram (DDR3)
AMD Radeon 6670 GPU (2GB DDR3)
Windows 8 64bit
450W PSU (STOCK)
VIBOX Gaming Case
Gigabyte 78LMT-USB3 Motherboard

AMD FX6300 6 CORE CPU (STOCK SPEEDS) 
 

I'm playing on a 60Hz BENQ 1920x1080p monitor. 

 

I would love to just replace my GPU since gaming is my main reason for buying a PC in the first place, however it turns out my pc GPU is so under powered that its getting its power straight from the PCI-E slot in the motherboard! my PSU doesn't even have a 6 or 8 pin connector to power a GPU!.

 

So basically I want a good powerful GPU that isn't crazy expensive and can give me a constant 60fps at 1080p. (and wont be bottlenecked by my FX6300) 

I obviously need a new good power PSU too, to power the card and the rest of my PC. 

 

Any help/suggestions would be Greatly appreciated!.

 

Thank you.

Get a decent 500W or so PSU, like a CX500 or something and throw an R9 280X in there. Its pretty cheap at the moment and makes a very good 1080p card. Anything above that won't perform at its best with your CPU.

750Ti due to the power supply being stock.

 

If the PSU has PCI-E power then get the GTX 960 or 270(x).

 

Or swap out the PSU but that is not always an easy task in branded desktops.

A 270x works well for 1080, will work fine with 450w psu and can be bought pretty cheap.

i'm gonna be getting a new PSU anyway probably a 750W, so 270x seems a little under powered? and since my current psu  dosent have connections for a GPU i'll have to

I just recently upgraded my computer and got a 750W PSU and sapphire Dual-X R9 280 3GB and it works like a beast. Haven't gamed on 1080p yet, but if you are worried to not get 60fps 1080p. I would look for a variant of the 280 or 280x.
