post some links of a computer that you think would be good for gaming and performance... probably one that comes with windows 7 pro. i5 or i7 intel, and some some high nvidia version in it. idk much of which one is best or what does a computer need to be able to play any kind 3D game in it and not lags and be able to play some pandora while playing and get no laggs. if its a laptop better. i prefer a laptop over a desktop. idk why.
THANKS FOR YOU GUYS HELP.
You will have to make some considerable sacrifices for a laptop. Namely, anything that will be able to play 'any kind of 3d game' you're looking at a desktop replacement, meaning that it's going to be huge and heavy. Anything with a decent resolution(1920x1080) probably won't be able to run some of the really demanding games on high very smoothly. These laptops typically also run into heat issues, as higher end gpus and cpus produce an immense amount heat under load, probably want a cooling pad and clean it religiously to prolong it's life. Not forgetting the fact that it will cost you much more money compared to a desktop of similar performance.
If you've got the kind of cash you originally cited, you're better off buying/building yourself a desktop, and spend the rest on a decent midrange laptop. Worst case, you probably won't be able to run Skyrim, but it will handle legions with out issue, and i think you'd be much happier.
anyway here's a quick list of parts i'd consider.
intel i5 2500k (easy to overclock later down the road)
corsair h80 closed loop cpu water cooler.
p67 or z68 motherboard if you pan on using integrated gfx, quicksync, or ssd cacheing
8gb ram minimum
evga nvidia gtx 560 ti
1tb 7200rpm hd(depends on how much storage space you actually feel you need, system is expandable later)
dvd burner
win 7 pro
atleast 650w quality psu, higher if you plan on heavy overclocking and sli
case of your choice
I'm too lazy to choose the actual items for you, maybe later
