DDR2 isn't quite obsolete. It's starting to get phased out in the high-end systems, but it's still alive and kicking for now in the mainstream because it's so damn cheap. I mean dirt cheap.

I mean, just today, we were seriously considering putting DDR2 into a system to send out for a high-end system review. We ended up settling on DDR3 in the end because the mobo we decided to use (EP45-DS3R, which is a great mobo to use, btw), was a DDR3 board.

Ultra Chill- Tec-------peltier cooling,best way to go without water!desmith1231

Chill-tec is a waste of money, lol. It might cool slightly better than the basic no-maintenance water cooling kits (I'm talking maybe 1 or 2 degrees in my tests) but costs like $50+ more. You have to remember, though, that the Chilltec blows hot air within the case while a no-maintenance water cooler typically blows the radiator heat directly out the rear 120mm fan port--my tests were done in open air. I'd actually expect the chilltec not to perform as well within a case (Peltier is really inefficient and generates additional heat within your system)

Plus it comes with a completely worthless control box that fits in a 5 1/4" drive bay and has completely unrealistic temps (says my OCed Qx9770 4.4ghz runs at 27 celcius, rofl), and an animation of a man digging. Yes, a man digging. What a digging man has to do with cooling is beyond me, but not once have I seen him stop digging or dig any faster. It has a lot of pretty colored backlights, though. So if you like pink, purple, blue, turquoise, or green, I guess that's a plus.

Ok yeah I'll ask about building your own, I'm just completely lost on how to physically assemble everything. And for the Dell I can't get HD4870 cause they don't have that as an option. Would you recommend the parts I listed above or is there something better? kwonny

Well, putting together a computer is like putting together a really expensive jigsaw puzzle. The only thing you sometimes need to apply some force to is mounting the heatsink (you want a snug fit).

1gb is enough to install Vista. I don't think we offer 512mb modules at iBuyPower.

512mb should be fine for now and is there any paticular reason your buying from those two sites ? There considered by many to be practially the worse place to buy a computer because of there awful customer support which pretty much voids any warrenty and many DOA stories. Also if your not careful they will skimp out on parts, for example they will give you a good card/ram but then slap in a generic apevia powersupply which probaly couldn't output 1/2 the amps it says on the box. mastershake575

I cannot vouch for Cyberpower, since we are a completely separate entity, but at iBuyPower, we offer power supplies from reputable companies such as Corsair, Mushkin, and CoolerMaster. The choice is made by the customer, not by us. Every system we ship is tested to be working before it leaves the factory floor. We cannot, however, control what happens during the shipping process.

Go liquid if cost isn't an issue. There are some good no-maintenance liquid kits out there that are very effective.

If you're set on air cooling, though, go with the Tuniq Tower.
