If you want >3GB with an x86 PC, you really need a 64-bit processor.

If you want power, then consider:
moderate: Intel Core 2 Duo
more: Intel Core 2 Quad
best, but expensive: Intel Core i7

If you want to keep the cost down, then AMD do some quite reasonable
chips. The Sempron 1200 series are very cheap & still 64-bit capable
and the Athlon 64 X2 range offer inexpensive dual-cores.

Once you get to the point of spending as much as a Core2 would cost,
though, Intel gives better performance.

Don't forget, when comparing pricing, to compare the cost of the CPU +
motherboard + RAM. No point in buying a £25 CPU that needs £200 of
motherboard and memory.

I recommend *avoiding* Intel Celeron, Intel Pentium and any other
Intel chips /not/ badged Core2 or better. The Celerons and Pentiums
are crippled Core 2s, with half or more of their onboard level 2 cache
turned off. This dramatically reduces their performance. Yes, they're
cheap, but you're paying for a product which often cost as much to
make as the more expensive, faster versions but was deliberately
hobbled to capture a lower price point. This strikes me as unfair
business practise and I won't touch them myself.
