[H] Quad GPU review (590 SLI v 6990 CF) *56k warning* - Page 14

post #131 of 134
I'd love to do some testing on my computer using the SSS and also the HDD for install media. The only stipulation would be that I'd have to find a test that could max out 1.2gb memory with 1080p to prove/refute the point.

[QUOTE=Defoler;13629379]Todays enthusiastic gamers, with multi-GPU setups (or dual GPU cards), will have a minimum of 4GB, while most likely much more (6 or 8 at least).

i thought vram doesnt stack. so 2 cards @1.5 gb vram would still only be 1.5gb vram. im confused why people are saying 1.5gb when referencing the 590 though. isnt it 3gb for the 590 and 4gb for the 6990? thinking of selling my lightnings for the asus 590 if its really 3gb and not 1.5gb vram. anyone know?

The amount is split between both GF110 chips on the GTX590 so you have 1.5BG per core. The HD 6990 has 4GB split so 2GB per core.

It's 1.5GB on each core, meaning your 580s have the same VRAM and more OC headroom and faster performance.
