I found a deal on a GTX 275 for $80, and I already have a GTX 275. I want to buy it so I can SLi them, and boost the frames in the games im playing a ****load.

The rest of my PC is:
Core i7 920 @ 3.8GHz
OCZ 6GB DDR3-1600 Obsidian
700W OCZ PSU
750GB Western Digital 7,200RPM
Asus P6T X58 mobo

and my case is a Cooler Master CM 690, which looks like the second would fit fine.

Anyways, my question is how would the performance of GTX 275 SLi compare to a GTX 470? Would the 470 **** on it?

I read the 470 has 440 stream processors, and the 275 SLi has 270 or so, so by SLing them it would be like 400 or so, and also the 275s have 448bit memory, while the 470 has 320.

What do you guys think? Should I get the 275 and SLi for $80, or wait for the 470 to drop in price and get that.
 
Wuts! 80$ for an 275 lawl!. Buy it dude and u can sell your 2 275 for 1 gtx 470/480 if you are not happy with the performance/fps

Good call bro. Its used thats why I got such a good deal, I'm sure the performance will be great, it just wont have the percs of a 470 like DX11, but whatever I can live without that.
 
That's a steal, and as for performance it will most likely depend on the game. There are no direct "GTX 275 SLI vs GTX 470" reviews so far, but by indirectly comparing numbers from the reviews I've seen, the 275 SLI will give similar or higher performance in most games; except ones with bad SLI scaling.

for now, find out the difference of the FPS for a single 285gtx and 275gtx. then look at the SLI performance for the 285gtx then subtract the difference from the single gpu comparison of the 285 and 275 and there you have it. a Rough estimate of the performance of the 275gtx in SLI. Some of the benchmarks shown are for DX11 and/or are new for Anand and own show recent GPU's in the test. But for the test that are showing the single 275 and 285gtx. the difference in FPS is very small. 4-7 average FPS difference between them.

I was going to go from my 285gtx to a 480gtx but i thought it would be very stupid for me to dump 500 bucks on a 480gtx when i could get an other 285gtx and SLi and guess what, i did just that !!! I just received my 285gtx in the mail today and i have to say I'm very happy with my decision. The benchmarks shown by anand show the 285gtx sli set up getting 10-15 MORE fps than the 480gtx in most tests and 25FPS and up more in a few test !!! (mass effect and an other game).

the 275gtx has 448-bit memory while the 285gtx has 512. As well as the 275 only have 28 ROP's while the 285 has 32. TBH. i think you should get VERY close results with the 275gtx in SLi as what my set up gets and mine beats a single 480gtx!.

I would TOTALLY go for an other 275gtx. Just be sure to install the latest EVGA SLI enhancement patch once you install the other card if you do go for the 275gtx (which you should)

For 80$ you can't go wrong, Even with a few games out there with poor SLI scaling at a minumum ive seen as little as a 20% gain. But in a few games ive gotten near 100% scaling. I've got 2 tri-sli rigs atm, one on loan to my brother
till he gets the rest of his parts. 3 GTX 260 core 216's in this box and i have very little trouble cranking the **** out of the eye candy. At the very minumum even if the game doesnt have great support for multi-GPU you can crank up the 16xQ SLI AA and see little or no slow down. I have BC2 for both PC and Xbox and honestly when going from the Xbox to the PC @1900x1200 with all the visuals cranked i almost wanna sit and drool at the detail.
 
Thanks for the advice guys. I threw the second GTX 275 in, and put the 3-way SLi that came with my P6T on. WOW. My FPS in Bad Company 2 went from 40-80 to 80-150, with full 16AA and 16AF. Granted I only have a 19" monitor. I have both cards overclocked to 700core 1225memory 1518 shader. There were no problems with one being by BFG and one being by EVGA. Both cards have lifetime warranties. I feel like the GTX 275 SLi feels equivilent to a 470 or maybe even a 480 since I OCed them.
 
I never reccomend SLI unless its 1920x1200 AT LEAST, but that is a great deal....If you are only on a 19" monitor though, even that $80 sounds like a waste to me. Tough call.
 
Yeah, with prices coming down im hoping to get one within the next month. I saw a 23" 1920x1080 monitor at Microcenter for $149.99
 
A gtx295 is, roughly speaking, two 275s.
A 470 doesn't beat a 295 (a 480 barely does), so two 275s will almost certainly beat a 470.

Plus, $80 is a crazy good price for a 275 anyway, i'd buy it and try it, and if i didn't like it sell it for more money and buy something else.
 
Agree, $80 is a total steal! Give us a link so we can all get one :)

Bob, interesting reading your comments: a 480 barely beats a 295? Seriously? If so, you have answered my question friend....
 
It's roughly the same 5-10% it beats a 5870 by, as the 5870 and 295 are extreme close performance wise.
In brutally tesselated stuff (you know, the games that "are coming") the 470/480 pull further ahead.
