9800gx2?

the guy on tiger tv said that you can only run two in sli not 3 cards with the 790i or 780i is this true??

Yes typically you run two cards in SLI. I just checked on the 780I, it does have three PCI x16 slots but I don't know if you can run three cards in SLI. Even if you can, you don't need to. One card is plenty to run any game out there.

on the 790i you can run three cards im just wondering though if that specific card will work having three of them or is only 2 the limit

Only two.

so if i wanted like the most advanced system it would be a waste to get a 790i because i couldnt use 3 of those and only 2 ok thanks!

If you bought even one 9800GX2, you'd be throwing your money away.

The most efficient price/performance is two 8800GTs or 8800GTSs.

would three 8800GT ot GTS be better then two 9800GX2?

I would say two 9800's woul be better then tri 8800's.

Some people have had problems with 9800GX2's in SLI due to driver issues.You can't run two 9800's in SLI as only four graphics processors are supported I think.

Still, there really is no point in getting them. Go with two 8800GTS and be happy!

The nForce 790i is a beast of a motherboard but is pricy. I built a system for someone around one and had no problems with it.

even though the 9800gx2 is 2 8800gts the 512mb version what about the 1 gb version? you would have 1 less gpu but a 1gb more ram

i have the 780i which is the ddr2 790i and it rocks

extra vram would be useless

so is it true that the video memory really doesnt matter just the clock speed?

Well, it matters somewhat. For example, the 512MB 8800GT will outperform the 256MB one at most resolutions. Resolution and AA are really the big concern as far as VRAM goes. 320+ is the min you should be looking for with a 1280x1024+ monitor (1440x900 widescreen), 512 should be sufficient for most high res stuff.

I can't imagine anyone needing 1GB except for the case of 2 GPUs (like on this card). You could argue it's for ultra-high resolutions, but most of the smaller 1GB cards like the 8500 can't game anyway and I don't think such VRAM is useful in media center apps.

ok thanks sooooo much for all of your help carbon

no problem
