hello people of toms hardware. i kinda wanna upgrade my cpu and video card. i currently have a corsair vx450 psu with a athlon II 250 and asus 4850 video card. my question is can i upgrade to a phenom II x4 965 cpu and a more powerful video card. i think i can do the cpu upgrade but the thing im worried about is the video card. if you kind folks can help me out with some options i would have that would be better than my current setup. any help would be great.

I would go for a 955 rather than the 965, cheaper and still has the unlocked multiplier, take the money you save and get a heatsink like the cooler master 212+ and OC it.

As for the GPU, what is your screen resolution? A 5770 is about as powerful as you can get on your current PSU, a 5850 would give a far more significant boost in performance but really should be run on a more powerful unit than a vx450.

is there much off a difference in the 4850 vs 5770? also my screen res is 1366 x 768 right now. but i plan on getting a better in the future. girlfriend got me this one as a present so i didnt bother spending extra money on a monitor. what resolution would the 955 or 965 and the 5770 be playable at

The 5770 is marginally less powerful than the 4870, which is a fair bit better than a 4850 but not enough to warrant an upgrade to one. The 5830 is the next reasonable jump but it consumes more power than the 5850 and doesnt cost that much less.

wpuld just the 955 or 955 make a huge difference in gaming?

Your CORSAIR VX450 is an amazing PSU which can handle a phenom II x4 965 and even a 5850. It's no necessary to change it.
