There shouldn't be bottlenecking, though it depends on what resolution you play on.

if you are gaming at 1680x1050 with no eye candy turned on then yes you are bottlenecked, if you are gaming at 1920x1080 with eye candy turned on then you are fine

eye candy: AA,AF,High Particles

Well, thats good, seeing as how I love to have eye candy on and I run at 1920x1080.

PS. My current computer has those listed specs, except I have an HD 6570 instead of HD 6870, which I am about to buy. How big of a difference should I see if I run BFBC2 and SC2 at 1920x1080 with eye candy if I switch from the HD 6570 to the HD 6870?

5570 and 6570 are pretty much the same

"Bottlenecking" can be highly over-rated. A good quad core processor won't keep the graphics subsystem waiting long enough for you to even notice in normal gaming. You're usually only talking single digit FPS differences.
That being said, your Athlon II X4 630 is only in the Intel Core 2 Duo catagory as far as speed. So you will experience some loss of the card's true capability. But unless you are willing to upgrade your processor, I'd say go for it anyway. It'll be a major improvement over the HD 6570.

the only time you your likley to see a bottleneck is on an game that uses 1 thread as single threaded performance on that cpu ist stellar. the 4 cores together make it a pretty useful cpu for entry level gaming so it should handle a mid range card...
over all your gonna loose about 10% of the performance of the card compared to a system with a faster/better cpu. but thats no big deal if you can oc about 400mhz.

if you have 3dmark o6 then run it, if you clear 10,000 you have an entry level games machine. 15000 and your midrange so you can bump most settings to max at modest rez... 20K+ and 1080p is your playground...
