I'm aiming to spend <£200 on a new processor, as my 2.0GHz Pentium 4 no longer fufills my requirements.
There are numerous benchmarks, testing the two processors here:
Both have their upsides and downsides - which ought I get? I'll be doing serious 2D stuff, like Photoshop, Fireworks, Word etc. I don't download every game, but I do enjoy an occasional game of Rise of Nations.
For my budget, I could alternatively get an Athlon64 3200+, not 3400 - would this be a worthy investment?
