I just fried my GeForce 9280! My motherboard is an Asus P4S8X with Sis648 chipset.Does this mean I should use an AGP card? Can I use a PCI-express card? I am currently leaning to the Ati X850 pro 256mb AGP or the GeForce 7800 GT OC 256mb. The burning questions are:Should I stick with the AGP cards? Will my board even run a PCI-Express? Is there a better card I should be looking at. I am a heavy game player!! I need a high fps--Lagging flips me out!!! Any advice will be extremely appreciated. Also I need to Know if my power supply and cpu are adequate for a more powerful board.I have a 2.4 and max of 12v.
