GA-790XTA-UD4 and dual VGA card question

[Naxterra]

Hello

I am thinking to upgrade my current VGA Card (ASUS GTX295) to better one with Dx11 support. I am currently looking at ATI 5970, nVIDIA GTX460 SLI and nVIDIA GTX480.

My question is does this motherboard supports SLI? I know it says crossfire but can't I install nVIDIA SLI?

My budget is like 600 euros and really want a high end graphic card on my system.


My spec is below

AMD Phenom II x4 965 Black Edition CPU
Gigabyte GA-790XTA-UD4 (F4 firmware)
ASUS 295GTX
OCZ 1600 MHz DDR3 8GB RAM
Seagate 500GB HDD, Seagate 1500GB HDD, WB 640GB x2 RAID0 HDD (All SATA II)
Corsair 60GB SSD
Highpower 850W PSU
Coolermaster CM690 High Tower



Thats my system. can I get SLI GTX460 or do you recommend something else?

Hi and welcome to the Gigabyte Forum.

As far as I am aware the AMD boards only let you use Crossfire and not SLI (I am sure absic will correct me if I am wrong) so you would only have one option in that case. The 5970 is the best card out of the bunch anyway and a real beast. If you are considering crossifring two of them in the future you are going to need a lot bigger PSU to power them. Your present one might be enough for one card. It would be some system though with two of them.

Hmm I can crossfire x2 5870 but not x2 5970, it will drain all of my savings.

So I can't do SLI which is better now?

x2 5870
5970
or
GTX 480?

or new 6000 series?

I really don't know enough about the 6xxx series yet. The 5970 is a dual GPU card already but only uses one slot soI would think that is better than two 5870s in Xfire.
