A64 3500+ venice + PC4000 or low latency ram + X800 XL + overclocking = Best system for the least amount of money.
This may be true if you plan on overclocking. However, if you plan on running stock speeds you would be better off putting the premium you pay for low latency memory or memory that can operate beyond the official specifications towards a beefier CPU (or even a stronger HDD or mainboard). You may be able to purchase a 3800+ and "plain boring DDR-400" at the same price as a 3500+ with low latency/PC-4000 memory. I would recommend the faster CPU option.
