Quick SLI question, 7950gt

post #1 of 14
Thread Starter 
hi all i currently have a 256 mb 7950 gt in my rig and want to improve performance without spending too much. I am considering another 7950 to run in sli with my current 256.

I would like to get a 512mb 7950 as the second card and zm curious if i could utilize all the memory of both card. But considering the original card is only 256, Would my system be able to use all 768mb ram or would it only use 256 of the 512 beause my original is only 256?

just upgrade to a more recent card. that will consume less power, produce less heat, and give more stable and faster performance.

thanks for the replies!

A friend of mine has a 512mb 7950gt laying around and i could acquire it for very cheap as opposed to a new card all together. I was under the impression sli utilized both cores AND memory.

So running cards in sli mode basically just uses the second core and not the memory? I fried my gtx260 overclocking with stock cooling so im hasty to spend $200 more on a second one for the amount of gaming i do on the rig.

A single 260 or an HD4870 will trounce two 7950s and you won't have to deal with SLI.

SLI is not worth it with that card.
As many other users have said, just pick up a GTX 260 on the cheap.
I'd sell you mine at a good price if I had enough rep.

You could pick up a 9800GT or GTX for less than 90 bucks now. They will do the job you seem to need. A 7950GT is no longer worth what your going to pay. Unless your just web browsing it's not capable of playing today's games.
