Upgrade Graphics or CPU?

Personally, I would go for the 7870 since the upgrade in performance is going to be much higher going from a 6770 to 7870 then you will upgrading your CPU. Honestly, the Bulldozer/Piledriver series is over-rated. What games do you play the most. If you play graphics intensive games like BF3 then the 7870 is the better choice since most graphic intensive games are proven to be GPU sided.

I prefer GPU too.

GPU the 1100t is a perfectly good processor for gaming 7870 would be an ideal up grade you wont notice to much difference between the processors .. how ever you may want to consider that your going to want at least a 500 watt power supply to drive that system

i have a 600w power supply

7870 for sure. That cpu upgrade isnt going to do much for you especially not game wise.

i asked about a Graphics card yesterday. What I got was 7870.... or wait. I'm going to wait for the 8000 Series to come out which is going to hopefully come out at the beginning of 2013. It is supposed to be 40% better than the 7000 series and it is said to be about the same price as the 7870. So if you can wait (Like I can) I would recommend doing so.

Tbh if its in your budget and you value your hardware i might consider upgrading your psu. It says 600w but thats not always the case especially with that series of psu. Google it there isnt much good on them. For the same price as that particular psu you can pick up a 500+ w psu from say antec, seasonic, corsair, or pcpnp.

Only a suggestion ofc my old 500w cooler master psu was weaksauce and underpowered when i last upgraded and its noisy as hell.

The new GPU will provide more of a performance boost in games than the CPU. The Phenom II 1100T is fine for gaming. I'd save he CPU upgrade for last.
