I've built myself a new main PC based on a Core 2 Duo E8400 and an Abit IP35 Pro XE. Here's the full article on the components and the build. I built my previous machine back in 2004 and was still running a P4 2.8 Northwood so I figured it was about time for an upgrade.
I've also made the move to Microsoft Vista Ultimate now that Service Pack 1 is out. The Windows Experience Index rates the overall hardware at 5.7. Everything is 5.9 except the E8400 which is 5.7. Complete rubbish! It should be 5.9 across the board.
Looking forward to overclocking it once I'm sure it's stable. I'd like to get it to 3.6Ghz and maybe even 4.0 like many others have.
