AMD FX-6300 Vishera good for Gaming?

That cpu won't be holding you back. It's going to be your 550 Ti. There are better Intel processors but if you're only gaming at 1080P then perhaps you should upgrade your gpu too. Nothing extreme. A new 7850 or 660 will run perfectly at 1080P.

Agreed your GPU isn't very good, you might consider upgrading that instead.

Well.....
Yes, depends what your aiming for, but it can be a good gaming processor.
But 50+ FPS is a maybe, depends on texture detail, the 550 ti will be holding you back; if anything.

I recommend making a jump to the 7XXX series, preferably a 7850, a good card.

Yeah, the only thing holding you back will be your GPU.

yep get a 7850 atleast before you get the 6300

Whats your current CPU?

I'd sell that GTX 550(If you can) If I were you, and get a better GPU first. Like above said go for a 7850 or 7870

I'm running the FX6300 on a Gigabyte 990FXA UD5 board with 2 7850's in crossfire. I've had to run BF3 on auto to achieve an average of 60fps in 1080p. It's a great processor and I'm glad I picked it over the 955 Black Edition.

I have a fx 6300 + 8gb ram @ 1600mhz + GTX550TI

All settings on low @ 1920x1080p I get average of 58FPS in a 64 player map on conquest LARGE. Same as with CANALS with 64 players team-deathmatch I get an average of 62 fps.

I was hastling to get a new GPU or CPU/ram/mobo. I got the new cpu/ram/mobo and it gave me amazing FPS boost, former FPS was average 25/40, now its 58 to 88 FPS (low settings ofcourse)

If you want to play games at higher settings and a better FPS, I advice you also to get a newer GPU.

Hope this helps you out
