I have an OC'ed 2.8Ghz 2 gig pqi Ram, and a 6800 GT 256mb card (will be upgrading that at Christmas I think, newer cards are cheaper now)
Now... If I could just get 2 10,000 rpm Raptors..... (although they are LOUD and hot) but sooooo smooth. Hard drives are the PC's bottleneck.
We need Magneto-Crystalline Disks. Near instant read/write.
And then Windows Operating system on a chip on your motherboard. Instant boot OS. I bet that's coming in 5 years or so.. (that would kill pirated copies huh)
