I was just wondering was this for a new build or will you be using any leftovers from an older PC?
I myself just built an AMD FX 8320 + HD 7850 rig and am overjoyed with it.
If you have a good budget... grand or better you have plenty of options. If your going on the cheaper side focus on the primary components first. Maybe you don't really need the SSD or blu-ray. Anyway, I'm sure you'll get what it is your looking for if you research and shop around.
I had seen a few bundle deals like this ----->

Had I gone that route I was considering an Nvidia GTX 660. Which would be pretty awesome.
With something like this bundle I would make sure I got another 4 gigs ram (8 total) at least a 120 gig SSD (boot drive) and a Blu-ray multi disc-drive
I am not a fan-boy so much of anything but performance and I can say I definitely did alright with what I got. I was shooting for just under a grand USD for a made from scratch rig and I shopped around and made my budget + got the extras. The bundle plus extras would put you around the $1000 mark pretty quick. And that's to say you have Monitor, Keyboard, mouse, etc...
I really was going for a GTX 670 but the Radeon 7850 made the budget happen for me and it didn't let me down.
Pretty good bang for the buck.
Like HawJin posted earlier it can OC to 1050MHz Core and 1450MHz Memory easily without a problem and my Gigabyte card never even gets above 65C under full load with just stock cooling. I've only seen it that hot while burn in benchmarking it and that was for 20 minutes.
Well whatever you do I hope you have fun with it and I can tell you it will be worth it.
