Which cpu would be fastest?

[Energize]

At the max stable overclock on air, would the E4300 or 3800+ be faster, and by how much?

I can get the athlon for £60 del and the intel for £98 del, but I'm not sure which route to go. How does the future look for intel and amd? And how futureproof is socket 775 vs am2?

The cheapest I've seen it is £115, and it's £130 here.

I'm on the tighest budget you could imagine.
