alright, first off, no I havent built a PC yet. but ive moved the internals from one to another case, Ive replaced HDD's, upgraded CPU's, upgraded RAM, installed dvd/cd drives, pci cards, etc... I mean, Ill never be able to say I built one until I build one, so just the fact that I havent yet shouldnt stop me from doing it now. MSI 785GM-E51 AM3 was looking at an asus ASUS M4A77TD AM3 but no eSATA port, although I probably wouldnt use it... also I know when I read the P55 motherboard shootout, ASUS had used older chips to run stuff on the PCI bus where other manufacturers were running them on the PCI express bus. I gotta read on that some more. AMD Phenom II X3 720 2.8GHz pretty set on this Crucial Ballistix 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 SAMSUNG Spinpoint F3 HD103SJ 1TB 7200 RPM 32MB Cache LITE-ON Black 24X DVD+R 8X DVD+RW 8X DVD+R DL 22X DVD-R 6X DVD-RW XFX HD-577A-ZHFC Radeon HD 5770 1GB 128-bit GDDR5 PCI Express 2.0 x16 which is more important to consider, dirextX10 vs. 11 or 128bit vs 256bit? COOLMAX V-600 600W ATX12V Power Supply Linkworld 313-07-C2228 Black/ Silver Steel ATX Mid Tower for a cooler I was thinking of this Thermaltake SpinQ Performance Series cooler is something like this actually of benefit? I know in theory it is, but does it really do anything worth while. COOLER MASTER SLC-S41-U1 Copper Fan & Heatsinks I wont be buying the stuff right away, but I hope to not wait too long, but the longer I do wait, the cheaper all this stuff should be anyways. as of right now it all works out to just below 700 bucks. I will have to get a new monitor also, because I still have an old 17" from 1998, but asus has a 19"LCD for 110 shipped, might get that one. also, I do plan to OC this setup, any potential problems with any of the components I picked out?
