Help with a new build (ish)

[s3curity]

hello. I have recently been looking into a new PC to run BF3 and BL2. Since I do not have any experience with building a PC yet to have good performance with these games a prebuilt is not an option, I was thinking about buying a stable base PC (i5 2500k probably for CPU) and then installing something like a GTX 560 Ti as an improved graphics card. My problem is I need suggestions for a base PC with a preferred i5 2500k and at least a 1tb harddrive. Suggestions would be wonderful. Many thanks

oh an edit thanks to macgreen
Parts to Upgrade: GPU as stated

Do you need to buy OS: No


Preferred Website(s) for Parts: hmmm well newegg is my preference but I live in America so probably something that is based here.

Location: City, State/Region, Country - upstate new york

Parts Preferences: GeForce idc as long as it can run BF3 at a reasonable fps

Overclocking: Maybe

SLI or Crossfire: don't exactly know what these are but...

Your Monitor Resolution: 1024x768

Additional Comments: BF3 and BL2

And Most Importantly, Why Are You Upgrading: nothing on newegg can run BF3 without tons of bluescreens apparently.
