Will PC3700 memory benefits on PC3200 Mobo??

[CP]

Hi all, most mobo these day can only support PC3200 DDR memory. What are the advantages I will get if going for PC3500 or above (PC3700, PC4000... Hyperam... etc etc)?

I want to buy Shuttle SB65G2 XPC, P4 2.8GHz 800FSB, 1GB DDR memory, Black DVD/CDRW drive and nVidia 5600 128MB. What can I do with PC3700 or higher?

Anyway, I have $1000-$1200 budget. Is there any better system suggestion with this budget?

Thanks

Memory rated higher than DDR400 (PC3200) will simply allow you to overclock your FSB and keep your ram at a 1:1 ratio. Motherboards only say they support up to 3200 because the highest non overclocked fsb is 800mhz. If you're planning on overclocking, memory rated higher than pc3200 will be a good investment, though not necessary as you can also keep your ram running at a fraction of the FSB (5:4 or 3:2). If you're not planning on overclocking, the best investment would be GOOD, low latency(cas2) PC3200 ram. I went with OCZ platinum PC3200, thinking I wasn't going to overclock my 2.6C, but ended up running the ram at a 5:4 with the FSB @240mhz, and keepign the ram timings tight @2-2-3-5...
