I would like to upgrade my video card from a 9800GTX 512mb to take advantage of my Asus P5Q Premium motherboard with Crossfire. However, for those familiar with the board, it only has 1 PCI-E 2.0 x16 slot. If I use both, according to the documentation, they both drop to x8.
So...here are my questions:
Assuming I buy two HD 5750 1gb cards and run them in CrossFire at x8
1. Will they greatly outperform the 9800GTX 512?
2. Is it worth doing CrossFire if they drop to x8 (in other words, would it be better to simply buy a $225 card to run at x16 vice two $150 cards running at x8?
3. Having been a long time Nvidia user because of ATI's driver support, has this improved - is it a good time to make the jump?
