This is a little over budget but you could pick up a cheaper case.
The 6970 is a nice card and I'm very keen on HIS IceQ versions of cards because they are significantly quieter and cooler than other manufacturers.
The case is all very subjective. I like Antec cases. I picked up this one because it has a USB3.0 front connectors.
The Corsair HX series is a great line of PSUs. These are 80 plus silver rated which makes them cheaper, cooler and quieter to run.
I wasn't sure if you actually needed multiple hard drives or not. 2TB are the optimal price / TB point right now so you should be picking up this capacity for hard drives. A lot of these drives are green drives and are less suited to being used as OS drives. You should use these drives purely for storage. That being said the F4 is one of the better performing green drives.
thanx alot mate will order them soon, the reason I needed multiple drives because I have a Huge Movie-Music collection which I want to store inside my Pc not on external drives, but will pay for an extra drive
rusting in peace makes some premium quality picks and I like them, but personally I feel that the GPU, PSU, and case are overkill, they are quite nice but all that for an i3? Personally I'd go with a HAF 922, Corsair 650W psu, and a 6950, I like the 2 TB drive that is a good drive and a good value but unless you are building a flagship I dont think there si a need for such a high end psu, case, and gpu, the i3 at stock will severely hold back a 6970 imo...even though Rusting In Peace's recommendations are top notch and it well under budget I think it is overkill for the OPs current cpu.
Rusting In Peace, I actually saved 1100$ my computer summer upgrade, I bought a VERY CHEAP case from a Chinese company called Sama, it had a psu as well and all that for 25$ so after a while it broke down and luckily the Mobo is still good, so Thats the reason I wanted a new Case-Psu But the case will cost me ALOT to ship here, So I calculated the shipping cost and most Mid tower cases would cost me 400$ in shipping, I needed a Gpu as I didnt buy one because my Mobo had one as I was told, So Thanx alot for your help jjb8675309 and Rusting In Peace , but before I leave I am thinking of buying a gaming BEAST and I want to be one of the people that brag about their computer so have you got any idea how much do I have to save for it? (Buying next summer)
