All, I am thinking about upgrading my computer. Currently I have an ATI X800XT and am looking at moving towards an SLI setup.
I'm thinking about going with the 7800GT in SLI Mode but am wondering if I am wondering how much of a benefit I will see?
Also, the cards I'm looking at are all PCI Express x16. In order to do SLI, I would need a motherboard with two 16x PCI-E Slots, right?
huh...there is no SLi in ATi, only
cross-fire which is not out yet to the public.
I know the that your statement was answered later but I have to call you out on this.
The OPs post unedited (and what you quoted) very clearly stated he was looking at a Dual 7800GT setup. It should be common sense to re-read a post if it confuses you, instead of looking like an idiot.
To the OP.
Yes you need a motherboard with dual 16x physical slots, and while future Intel chipsets will work you need a Nforce 4 chipset, either the original SLI version with 16x physical 8x electrical or the new SLI32 with dual electrical 16x slots. But as stated by another poster unless the performance isn't good enough for you I would porbably wait and see what the G72 and R580 perform like before upgrading. Their is a big performance difference between the 2 but for the most part both will handle everything well. Now if you are using a AGP version or can sell your current card, I would say go for it you will love it.
Edit: Under no circumstances should you get a 939 board with AGP. You have a chance to break out of a technilogical barrier don't screw yourself over by making any future high end purchases harder on yourself.
