PCIe 2.0 is backward and forward compatible with PCIe v1.x. Graphic cards and motherboards designed for v2.0 will be able to work with v1.1 and v1.0, and vice versa. In some rare cases it is possible that a PCI-E 2.0 card will not work correctly on a PCI-E 1.0a slot. This is only limited to certain video cards.

I have an Asus A8N-SLi m/board and am currently running a 7900 on it. It works OK but it is getting old and i have just brought a 8800GT 512M vid. Card. I put the card in and connected it all up but when i turn the PC on i get NO SIGNAL onthe monitor.

Hey guys I'm just gonna go straight to the point. Me and cousin have the same motherboard the a8n-sli vanilla(not deluxe, premium, or se). My cousin tried to install a geforce 8600gt onto his machine but it did not work.

I installed a 4850 into my PC a little under two weeks ago, and I have to say I'm not impressed. I haven't had an ATI card since a 9500, and I was very excited when I saw the numbers being benched on this card so I decided to take the plunge and switch. Unfortunately I haven't been able to get above 30-40 FPS in ANY game.

Here are my system specs.

AMD Athlon 64 X2 4400+
DFI LanParty NF4 SLI-DR
4GB DDR1 OCZ Platinum RAM
650W OCZ GameXStream (SLI Ready)

Vista Ultimate x64



I'm playing all games at 1280x1024 on a 19" Samsung Monitor.

Up until two weeks ago I had a 7900GTX, and obviously got more than 30-40 FPS in games so this should have been an upgrade. When I check GPU-Z, depending on the game, its using anywhere from 0-50% GPU and only in one case, in the WoW character selection screen, it uses 100%. I'm open to any and all suggestions. I personally don't think my cpu is a bottleneck here as its happening in many different games, and if anything WoW should be getting higher than 40FPS as that isn't a taxing game.

I should also state that my AA/AF settings, if set in CCC, do not work in games. I'm guessing this MAY have something to do with this all.
