Well, my grand plan to go Core 2 Duo has gone a little tits up as money's a bit tighter than I thought. Ah, well.
So... I can get a AMD64 x2 3800 for £60.
I currently have a single core AMD64 4000+.
Any point going dualcore for what, from the name alone, appears to be a slower processor? (leaving aside OC'ing issues)
