The HD5870 of course...

A few things amiss here... Core i7 920 usually uses Triple Channel memory, not dual channel (although it can be used).

If you have a lot of dough, the might as well go for Corsair TX 650W..

As for power consumption, these systems are.. errmmm.. power hungry. The electricity bill will be rather high when running 24/7.

@animekingz, if you want to run stuff like torrenting, downloading, etc... its much better to get a separate very low power PC (Intel Atom based) for that purpose. You can switch on your mega gaming PC when you need to use (e.g. play online games, browsing, etc) and access the Atom machine as a NAS machine (network file sharing) to read/move the files you have downloaded..

If you are using a LCD monitor with DVI and VGA inputs... then you can connect two PCs to the same monitor.

Note: Another reason I usually recommend monitors with DVI..

Corrected... saved at least another RM135..

Total: RM4515 - RM135 = RM4380

Sell the old P4 off.. to finance the Atom and your mega PC. Anyway, if 1.5GHz then its most probably a Willamette which uses quite a bit of power (the generation before the more efficient Northwood).
