haha, yeah, a big and expensive farce at that. Occasionally it works well but most of the time its just a headache - proverbial and literal depending on the cooler your card has!! Often with newly released games you get better performance disabling one card than you do with them in tandem due to stuttering issues. Search for 'Far Cry 3 stuttering multi gpu' for example and you'll be shocked by the number of problems. This was a game supposedly developed in tandem with ATI specifically for multi gpu setups (http://blogs.amd.com/play/2012/12/10/far-cry-3-in-depth/ and http://blogs.amd.com/play/2012/12/10/far-cry-3-in-depth/). While average frame rate roughly doubled with 2x cards, due to stuttering it was unplayable which single frame screen shots don't show. There were various fixes and there are 3rd party tools you can use to tweak the drivers to try to reduce the effect but FC3 was released nearly 3 months ago and they've still not fixed the issues in their drivers and its maybe not possible to completely eliminate it either due to the way the frames are rendered on multi-gpu setups.

I think because so few people actually implement SLI/XFire or other gimmacks like eyefinity, they can tout what ever they want and only about 5% of their customers are ever going to find out if it works.

If you want higher performance over and above the top of the line gpu then there is no option but to go for multi gpus of course, but until you reach this point, you're far better off with a single gpu.

Just my opinion of course, I'm sure there are people who swear by SLI/XFire but I don't think the ends justify the means and I've ran SLI/XFire rigs since NVidia 8800's way back when

I purchased a brand new gtx 570 for $199 new
a USED 7950 from what i see is like 300-325-350$

The performance increase for $125 bucks really didnt seem worth it,especially for a used card...


Maybe you and i have different oppinions on what "a few bucks more" means?



###Edit:### Ok,well ive searched around, and i DO see that you can buy a new 7950 for 279 after rebate..

which i assume,.you could probably get a used one for 230 or 250 im sure.. but, i dont know,i just figured the new one would be a better choice... Plus i do think i will take advantage of cuda at some point,i want to try it for the video encoding....
