I think AMD dual cores will be lot better than Intel's 8XX series. Go for AMD ATHLON X2 3800+[8k] along with ASUS A8NE mobo[5.5k]. It features:
* nforce 4 ultra chipsets with lots of overclocking options.
* 1*16x PCIE slot for Graphics.
* 2*1x PCIE for network, sound etc cards.
* 1*4x PCIE for Physics nd sound etc.
* 3*PCI slots.
U can use your old HDD PATA and u can also run your old DDR 2x 512 in dual channel in this motherboard. The board is rock solid.And the 3800+ is better than a 3.2 Ghz Intel 8XX dual core nd overclocking it is a piece of cake.
As gor Graphics card u can either go for:
7600GS 256 DDR2 for 7.5k
7600GT DDR3 for 11k.
The GT varient is much better than GS and is surelly worth it. But even the 7600GS is better than a 6600GT 256, and the 7600GT is better than a 6800GT256.
