Am I bottlenecking my video card?

Alright so around January I got a new PC (Prebuilt) and shortly after put a new video card in it as it was running with Intel HD. I got the 6670 as it was the best card that I could get without upgrading the power supply. So far I can run most games without any problem but a few are giving me some troubles (Crysis 2 and TERA mainly.) but Ive watched videos of people using this card and run those games at almost max settings with no issues. So basically Im here to ask if my CPU is the problem...

Radeon HD 6670 1GB GDDR5

Intel Pentium G620 2.6GHz Dual-core

If that is the problem what would you suggest I upgrade to? Thanks.

1. Run a few benchmarks, even the windows experience then compare with other 6670s and G620, make sure you don't have another issue like bad driver, malware, etc.

2. Here is a G530 system putting up some nice numbers. G530 is slower than your G620. http://www.tomshardware.com/reviews/gaming-pc-do-it-you... So yes there are games where G620 will be the limit, but with HD6670 you won't fine many where video isn't the limiting factor.

3. If you want to upgrade for gaming the first thing to change is your video card. The HD6670 was an excellent choice, however if you want more then it's time to change the HD6670 and the power supply. If new video isn't enough for you then you can upgrade the CPU, but most likely you need video not cpu.

4. If you post your model # & complete specs people can say stuff like "that bios supports an i5-2400 which would be a great upgrade" or "with that PSU you can get by with an HD7770" or ...

a 6670 is not a top end card, and a G620 won't bottleneck it. a 6670 will NOT run the most modern games at top settings. It should be fine at 1280x720, 1440x900, 1600x900 though, running at medium-to-high

Thanks for the reply. As for malware I havent had anything pop up and just scanned my PC Wed so I doubt that is it. Windows Experience Index is 5.9 Base Score, Gaming Graphics 6.9 and Processor 6.4 and all my drivers are up do date. My friend recently put together a PC with a 6870 and he says its running great so assuming I would put in a 6870 and i5 what kind of PSU would I be looking at?

Model: Lenovo K330B 7747-1TU

I got it from Best Buy but they do not sell it anymore so I could only find it on this site.

Specs-
Radeon HD 6670 1GB GDDR5
Intel Pentium G620 2.6GHz Dual-core
6GB DDR3 RAM
1TB 7200RPM HDD
280w PSU
Windows 7 Home 64-bit

So far I havent been able to find out what the motherboard is. I know its just a stock one but I cant find any info on it sadly.

Lenovo IdeaCentre Desktop

since it mentioned only usb2 and not usb3 in the specs, i think it is safe to assume its a H61 motherboard, so no overclocking.

for an inexpensive upgrade:
Corsair Builder Series CMPSU-430CXV2 430W $42.99
After Mail In Rebate: $27.99 USD

and a decent:
PowerColor AX7770 1GBD5-DH Radeon HD 7770 GHz Edition $119.99
$109.99 after $10.00 rebate(s)
$6.98 Shipping

that would be $170 upfront. now if you want a much larger card you would need:
CORSAIR Builder Series CX500 V2 500W $59.99
$34.99 after $25.00 rebate

at least to start with . . .

edit: your cpu now would handle that 7770 no problem.
