I have a new A7V8X-X mb with 512mb pc2700ddr, a AIW9700pro video card. I use this puter for everything, games, buning dvd's, and surfing the net. My question is is it worth 200 bucks to replace my AMD 1.8xp with a 2.8xp or 3.0xp.
Get an AXP 2700+, it cost only ~$100. There performance difference between 2700+ and 3000+ is ignorable, since they're equally clocked (3000+ has 512kb L2 cache, compared to 2700+'s 256kb, but it helps very little).
For $100-$110, AXP 2700+ is a good upgrade from AXP 1800+
