There's really no difference from a tv or monitor, I suspect it's 1080p? You're gpu is the weakest link but you could also get more performance if you overclock the cpu as long as you have a good heatsink. To test if your cpu is bottlenecking: in windows power management you can change the maximum cpu usage, put it to like 70% and see if you get a drop in fps. Testing if your gpu is easy, just change graphics options down and your fps should go up. What is you budget?
