Re: which of these 2 proccessors do you prefer guyz???
It's worth upgrading for down the road. The Intel Core 2 Duo offers many advantages over your current processor. It's highly overclockable, dual-cored so you can do more things at once, and is even better at gaming than a fx-62. I can see you're an AMD person, but this processor will change you!
Oh yeah, you might want to upgrade your video card if you want to play some newer games at decent framerates, without any choppiness. I reccommend the x850xt, or the 6600gt if you're on a budget. I know DX10 video cards are coming out but all the major video card manufacturers are going to release driver updates that make the card DX10 compatible, by software even if the card is still DX9 hardware. You might want to upgrade to 1gb of ram. Try to opt for dual channeled, like 2 sticks of 512mb and try to get the lowest latency possible in your price budget.
