Didnt think my other post go through sorry.

My birthday is coming up and I am looking to basically build a whole new computer with a few parts from my old computer thrown in. I am gonna get a new processor/ PSU/ graphics card/ motherboard/case. I did a little shopping around on newegg.com and this is what I came up with. Now just so you know, I am not the most tech savvy person out there, so any advice would be great. Now I might be able to stretch my budget a little if need be. I keep hearing comparisons on different brand names and different versions of a product (example 640mb gts vs 320mb gts, 650i mobo vs 680i), if there is a version that is superior to the one below please let me know.

Also I will be looking into overclocking some components.....when I know exactly what to do that is. I am a gamer at heart so I will be playing the latest and greatest games on this computer.

Last but not least. I tried to build  a computer last year and it didnt turn out so good due to my lack of research. So this time around I would like to get it right. Do any of you tech experts see anything that would cause compatibility issues or anything that would be  a problem?

Thanks in advance.

Ok, right now I am using my original 80gig harddrive i got when my computer was made and I recently added aa 250gig harddrive in for storage and whatnot. I have NEVER taken the original 80gb HD out and I am just wondering if I could replace it with another 250gb HD that i have laying around.

My computer only has 2 harddrive slots inside so I cant just add another harddrive i wanna get rid of the 80gig one but would that mean I need to reinstall windows and wipe both my drives clean or something? BTW both my 250gb HDs are SATA if that helps at all.

When does this come out? I read on some sites it doubles the speed of normal pci-e slots and am very curious when I can get my hands on something like this since I am gonna be building a new computer within the next few months.
