If you are planning on doing realy heavy oc'ing i would get some better mem. OCZ Gold would be the best, but if you want to save a little i would get either corsair 3500, or kingston hyperx 3500. You could take a chance on mem and get geil golden dragon, I got the golden dragon 3200 256mbx2 kit and i can hit ddr482 perfectly stable, and score over 6100 in sisoft memory bandwith benchmark.
I would also suggest you go with a western digital raptor hd if you want real preformance, but like most you probably don't need it and i would just go with a western digital pata 8mb cache buffer drive and save some money.
I would also say you should save some money on the mobo. either get a p4p800 or a plain ic7. that will save you quite a bit, and preform the same.
I myself am collecting my intel system now:
2.4c
waiting for ic7 max3
2x256mb ocz gold
r9800128mb pro
2x36gb rapter hd's
pc power and cooling 475w psu 30A on the +12v line(for mcw50-t)
fortissimo III
cooling:
mcw5000-pt
mcw50-t
86 chevette heatercore with dual wetwilly shrouds
eheim 1250, soon to be a rainbow and the 1250 will be for the gpu
I am going to wait for the ic7 max3 for the voltages. It has great vcore/vdim/vagp voltages. It also seems to have better cooling on the nb, and some corny looking little fans on the mosfets. I will probably replace the nb cooler because it doesn't seem to great. Anyway If i were to pick a mobo now i think the p4p800 would be the one i would go with.
