Great, thanks for the update. I thought of going the SLi route, but the motherboard cost too much plus I have to buy an additional video card which add more to the overall cost of the system.
I'm considering the Asus because of the overwhelming opinions regarding this manufacturer, but what about MSI? I'm looking at their PCIe 6600GT video card and it looks pretty good.
It's got the heat sink for the memory and the processor (actually a one piece heatsink design). I was reading the review and someone said the one piece heatsink design help dissipate the heat evenly. It also has overclocking potential too. I guess the drivers it comes with it has like an auto-overclocking button you can click to maximize it's performance.
...oh and what's the difference between DDR3 and GDDR3? ANy significant boost from one to another?
