I have been waiting to build a PC for a few months. After months of reading Tom's System Builder Marathons and Graphics card reviews I have put together a system I plan to buy in the few weeks. There are however a few things I am against the wall about.
1) I choose the ATI 4850 because I like alot of the results of its benchmarks against the 9800gtx. However I also read a lot of reviews about the card being extremely hot. I was thinking about buying a after market cooler but a good one is about thirty dollars. I had my eye on the dual orb and I am still not sure if I should get it.
2) I have no experience over clocking and I am unsure if it is something I should pursue or just stay with the out of box performance.
3) RAID. Should I RAID 1 the two Western Digitals. I potentially choose RAID 0 because 1.5 Tera bytes is a lot to lose if one drive dies. I have seen charts about the higher probability of hard drive failure if you are combing the chance of either of two drives failing.
I would probably Raid 0 the drives. Just know you're taking a risk. Fortunately, I haven't ever had a drive fail. The Asus 4850 is cheaper after the mail in rebate, at $158. Samsung has a faster 22X sata burner with Lightscribe for $28, look for it. I'm assuming that ram is 5-5-5-15. If not, look for those timings. Other than that, everything looks good. Whether you choose to overclock or not, you'll be fine with these components.
Looks good. Only thing I would change is the DDR2 1066, get rid of it for DDR2 800 (4-4-4, of course). Its cheaper, and basically performs the same as the 1066 in an intel system. You should be able to OC it to 1066mhz if you need to, anyways.
