Gtx 260
gtx 280
4850
4870
4890
gts 450
gts 250
9800 gtx
9600 gtx
5770


Need to know if you can but 4 of these cards in one system thanks.

Or are you better offer to go with 2x 9800 gx2, 2x 4870x2, 2x 4850x2, 2x gtx 295's thanks.

I would go with the 2x 9800 gx2, 2x 4870x2, 2x 4850x2, 2x gtx 295's , unless you have a motherboard with four pci-e slots if you can use two slots you have a better chance of getting four way. I would wonder if a three way of better cards wouldn't be better then trying to setup a fourway with the cards that you have listed. Don't forget that with SLI they all have to be the same unlike AMD/Ati/Radeon.
I'm thinking that two of the GTX 295 would be the best performance and the challange would be in finding these cards.

Also I can grab the 2 new 4870x2's for 130$ a pop while the new gtx 295s are 220 a pop.


FYI, Im doing a outdated build for a reason thats all im going to say.

But for the price gap and the little better performance on the 295's is it worth paying that much more, also what is the power req of 2x 295's and 2x 4870x2's the real power req not the stated one.

I guess the price gap makes it a better choice to go with the 4870's but I think that the reason for the gap is that the 295's are much better , However Tom's Hierarchy Chart has them at the same level.

The Nvidia site says that it draws 289w and recomends a 680w psu but I have never had one so you might have to research some old benchmarks that would say what the power draw is.

The 4870 draws 160w and requires a 500w psu.

In general dual GPU cards do not scale well in 4 way SLI....more than 2-way CF is for only the most adventurous.

The 4850, 4870, 4890, and 5770 can all do 4-way crossfire so long as a least 3 of the cards have two CF connectors. For the 4800 cards you can even mix and match, but it's best to get them the same. The only 285s that can do 4-way SLI are some special edition EVGA classified cards and EVGA also had a matching board for them. I assume they would work on other boards that support 4-way sli though but I can't say for sure.

Go for it. Let us know how it goes. Of course, the 3870X2s biggest problem was running out of VRAM at settings that would make use of 4 GPUs simply because it had 512MB per GPU. Also the PCI-E switch between the chips didn't help as I believe it was PCI-E 1.1.
