100 dollar csgo pc

[Sleeper PC 2016]

Im trying to build a pc that can run csgo at 80 fps minimum. Most pc's in my area are 3 ghz core 2 duo dells with 4 gb of ram going for 40-100 dollars. I found a dell with a 3 ghz core 2 with 4 gb of ram and now im looking for a graphics card. To keep costs down, i would like to add a low buck gpu. I may be able to score a gt730 for cheap on ebay or craigslist and sell it for a profit. I also found a 9800GTX+ for 20 bucks but the psu might s*** itself.  Which setup give me 80-100 fps on csgo on at least medium or high with no AA (options below)? After watching a few youtube videos of the gt710,730,and the 9800gtx+, it seems the cards get around 40-60 with the settings cranked up with AA on dual core athlons athlons and core 2 duos so i assume it can do 100 fps on medium with no AA. What do you guys think??

 

Option 1:

Core 2 Duo E8400

4 GB Ram

Nvidia Geforce GT710 or 730 1 or 2 GB

 

Option 2:

Core 2 Duo E8400 (same as Option 1)

4 GB ram (same as above)

Nvidia 9800GTX+ 512 MB

Possibly a different PSU (doing the math its around 250-270 watts assuming tower pulls 100-110 watts from wall stock)

 

Which option would be the best? The 9800gtx will sell soon so i need an answer soon

Either one will likely get the job done. Pick which ever you prefer.

but is it possible the psu will overload itself on the 9800gtx+? I dont have a wattmater on me and the dell's psu is most likely 300 watts. I do not have a psu more powerful then 300 watts

gt 710/730 would be better as the PSU doesnt need to be replaced

 

see if you can find a GTX 750/Ti used tho

cheapest i can find without paying 10 bucks for shipping is 40. I will try the 9800gtx+ or a 40 dollar gt730. Im guessing the 9800GTX+ will get better fps being faster then a gt730. Plus after doing the math, the 300 watt psu (assuming still) might take a dump.

 

I just googled this and dell psu's are supposedly made by Fortron or HiPro, a reputable psu manufacterer. No wonder my 250 watt dell psu from 2004 hasnt kicked the bucket.

@Ordinarily_Greater whats your opinion on this?

Ok got the Dell and the power supply is 305 watts, might be able to make it happen. Also there was an ssd in it as a bonus
