hey all, what i'm wondering about at the moment is a conflict between two processors. I'm on a budget and have found two decent looking processors and whilst i'm a PC enthusiast, i've never put one together before and am still getting to grips with some of the specs. I'm a gamer and so that's what the system is being built for. I've decided to opt for AMD's athlon 64 x2 due to the fact there are some great deals out there on them and they seem to be quite decent as processors. I know they're not as stable as intel's but i'm not building a supercomputer. Here are the two processors: AMD Athlon 64 X2 Dual Core 7750+ Black Edition 2.70GHz (Socket AM2+) £68.99 inc VAT - Dual-core Technology - 2.70Ghz clock speed (AM2 Socket) - Multiplier unlocked - 3.0MB Total Cache (L2+L3) - Cool & Quiet Technology for Energy Efficiency - Enhanced Virus Protection - 64-bit Technology - Hyper Transport Technology - Virtualization technology AMD Athlon 64 X2 Dual Core 6400+ 3.20GHz (Socket AM2) £74.74 inc VAT - Dual-core Technology - 3.20Ghz clock speed (AM2 Socket) - Cool & Quiet Technology for Energy Efficiency - Enhanced Virus Protection - 64-bit Technology - Hyper Transport Technology - Virtualization technology i'm not too worried about the unlocked multiplier, as i've not tweaked with overclocking yet. the 0.5GHz difference tells me the second wil run faster, but can anyone explain to me what the 6400+ and 7750+ values mean and are they related to processor speed? on top of that, what kind of value of cache speed would be a significant increase? Finally, which would you advise me on buying? Thanks very much for any replies, sorry i rambled on a bit.
