So now that I'm seriously considering buying a new PC and going through some posts here I think this is pretty much what I'm ordering:
COOLER MASTER Centurion 5 CAC-T05-UW Black Aluminum Bezel case
GIGABYTE GA-EP35-DS3L LGA 775 Intel P35 ATX Intel Motherboard
CORSAIR CMPSU-450VX 450W ATX12V V2.2 80 PLUS
G.SKILL 4GB (2 x 2GB) 240-Pin DDR2 SDRAM
Intel Core 2 Duo E8400 Wolfdale 3.0GHz
...along with a DVD burner and a 500GB HD, everything from Newegg of course.
I'm still missing a video card though, and although I'm leaning towards the 4850, I'd like some final input into some other sub $200 alternative I could be missing. I think it's mainly the heat issues it seems to have what worries me, although that fan trick does sound like a nice solution. I'm also planning to get a new 22" monitor along with the computer, so I guess that has to be taken into account too? I was also reading about the GeForce 9800 GTX+, but then again, I fear my knowledge (or confidence

) isn't enough to make a call or if it's even feasible with the motherboard I selected

. So, any help? I'm pretty much ready to go with the 4850 though.
Also, this all ends up at around $900 (with the monitor).
