i still have a case, hard drive, drives and a power supply. my question is will this all be good enough and will i need a new case or powersupply. i have a 450 watt from thermaltake is that enough, and i have a tsunami dream case. will everything fit in the case. suggestions? conflicts? thanks

Change the 9800 for a Radeon HD4850, instead.

And that PSU would be barely enough. A 550w one should be perfect.

Keep in mind that you'll also need a copy of a 64-bit Windows.

Other than the psu whch is not enough it's great.

if you can afford a quad core it would be excellent,but it's not necessary.It should have a fairly large lifetime in the way it is right now!

i dont think there is much point in going quad for a few reasons, price, worse in games (from what ive read cos i dont want to argue lol) and the new intel chipset is soon. but obviously the most important is that they normally out perform cpus like the quad q6600 in gamesrikjiallen

+ no heat problems and oc easier

the heat problems arnt all that bad all my friends have a E 8400/500/600 cards and no troubles as of yet, and the e8600 OC's a dream, but as i said this is just what ive heard and experienced and i dont know anyone with a q just read everything i know while i was getting my system

I'd go with a P43 board if you're looking to overclock. Biostar makes a good one: http://www.newegg.com/Product/Product.aspx?Item=N82E16813138122kodex1717

I have that board and I am going to RMA it. The layout is pretty weird, and the Northbridge heatsink is way too close to the CPU socket.

Get this one instead: http://www.newegg.com/Product/Product.aspx?Item=N82E16813138126

Also get a 4850 or 4870 and you're set. Make sure your PSU is decent though.
