GeForce 8400 GS vs.

I'm currently buying parts to build a new gaming rig... and I'm not too sure which video card I should get. I plan to SLI 2 video cards, either 256mb or 512mb cards.

Right now I'm deciding between:

A GeForce 8600 XXX card 256mb

SLI'ed with a GeForce 8600 GTS 256mb


an EVGA GeForce 8600 GT Video Card - 512MB DDR3

SLI'ed with a KFA2 GeForce 8600 GT Video Card - 512mb DDR2


2 XFX GeForce 8400 GS Video Card - 512MB DDR2

So what I'm asking, is:

-Which pair of video cards would perform the best?
-Can DDR3 be SLI'ed with DDR2?
-Can two cards that are the same GPU with different manufacturer's be SLI'ed together?

Thanks in advance!

I am not 100% sure, so don't completely go off what I say, but I have read that you need the SAME video cards to SLI. Can't SLI one video card to another different card.

which pair will perform best

In reply to: GeForce 8400 GS vs.

here's the cards ordered by performance.

to sli, you have to have two cards with the same gpu. you can't sli an 8600gts with an 8600gt.

but why would you plan to sli low-end cards? 2 8400gs will be slower than one 8600gt. and for $175 (less than the cost of 2 8600gts) or $200 you can get a radeon hd3850/256mb or 512mb that's as fast as two 8600gts. $250 gets you an 8800gt/512mb.

Thanks a lot, that was the information I was looking for. I'll probably just sli 2 512 8600's gt or gts then.

GeForce 8600

In reply to: GeForce 8400 GS vs.

The 8600 GT was a terrible buy at $150, but now, as it approaches the $100 price point, it's much more attractive. The 8600 GT will slightly beat the old 7600 GT and X1650 XT in raw performance in the $100 price category. In addition to speed, the 8600 GT has the added bonus of being DirectX 10 compatible, as well as being a good overclocker.

NOTE: Beware of slower DDR2 versions of the 8600 GT! The GDDR3 versions are the recommended cards, DDR2 equipped 8600 GTs will be notably slower. The cheapest GDDR3 versions of the card we could find started at $105 online.

Well the final decision is yours, but i will tell you this, Do NOT buy XFX, EVGA is ok, they at least have a 2 year warranty, however BFG is where it's at if you want nvidia products. BFG has a lifetime warranty, and that should say a lot about their products, since no one else even comes close to that, and their customer service is unmatched.

BFG NVidia Video Cards.....
