hey guys so i have a gtx 660 already i was thinking of sli as i have 280$ on my pc
if i want to sli i need another gtx 660 and a power supply atleast a 650w so its gonna cost me about 300$ but i can either buy a hd 7950 so what would you guys suggest 660sli or 7950? i am woried about the 660 having a 192 bit rate is that a issue (futureprofing) or should i go for 7950

thanks

Hello,

My opinion would be to go with a 7950, Some people here might not say so but for the price and performance , Its not a bad deal at all,! and its not like the cards are horrible they are great powerful cards!!!!!.

ps- the 660 sli will score a little better though!

192 isnt going to affect you unless you more than 1080p single screen gaming. Triple screen 1080p, or multi screen 1440/1600p....

If you are sticking with one screen at 1080p or less; 660 SLI should do fine.

OP what CPU, PSU and monitor do you have. which country are you from ? I recommend a HD 7950. at current prices its a steal.

Farcry 3 1920 x 1080 Ultra 4x MSAA

HD 7950(1150 Mhz) - 45.9
GTX 660 OC (1228 mhz) - 32.8

HD 7950 OC is 40% faster. Farcry 3 is a game where Nvidia does well. In games like tombraider, hitman the gap is 50 - 60%. on avg HD 7950 OC(1150 mhz) is close to 50% faster than GTX 660 OC(1200 mhz). SLI scaling on average across many games is 1.6x. so GTX 660 OC SLI is not going to be a huge gain over HD 7950 OC. moreover cooling a single overclocked GPU is easier than cooling two GPUs overclocked. power draw will be lesser with HD 7950. as a single GPU HD 7950 provides more smoother gameplay and more consistent frametimes. the HD 7950's gap widens at higher AA settings like MSAA 8x or SSAA 2x / 4x. the extra 1GB VRAM adds a bit of futureproofing as next gen games over the next 2 years can exceed 2GB even at 1080p.

grab this sapphire card when it comes back in stock.

whats the amps on the +12v rail of CX 500. 37A - 38A is what I would recommend as a minimum. anything less i would suggest a high quality PSU like a rosewill capstone 450.

660 would perform better for most needs but a 7950 isn't a bad deal right now at all. Honestly though. I'd wait at this point, keep the money you have and then when the 9000 series comes out, sell the current 660, take the money you have now and the money you get from the sale and then buy a new card.

I had the same choice in mind when i upgraded. I chose the 660s because its way stronger than a single standard 7950. But also my setup was already fully prepared for sli. And in my country the 7950 costs more than buying 2 gtx660s. Was a no brainer
