What to upgrade on my PC

[Lunzium]

Hi there, i was just wondering if any of you have any ideas as to what i need to upgrade to run my games on max/ultra (those games being Hitman: Absolution, CoD: BO2, Skryim, War of the Roses and WoW) while keeping in mind that i also use the computer for heavy 3D programs such as Maya, 3dsMax etc. I haven't got a really good grasp on the finer points of computer specs etc. i've pulled this info from the Steam System Information.

I'm guessing you have an i7 920 from the speed,cores and the GPU model paired with it(Just to be sure you can check the CPU model here: Control Panel\System and Security\System). The thing you'll want to upgrade would be the GPU and maybe the PSU if the one you currently have is too weak. Open the case and look for brand and model or the wattage of the PSU. I would be good to tell us how much money you'd be willing to spend.

Your GPU to a single strong one, and an aftermarket heatsink to overclock that CPU.

Yeah it's an i7 920, sorry bout that.

Okay so what i get from this is that i should replace my ATI Radeon HD 5670 and possibly my Power supply unit? (btw how do i know if my PSU is too weak?)
And about the money, well haven't really thought about a spending limit :P as long as it allows me to play my games on ultra and wont be outdated and antique in 3-6 months i'll just have to try and raise the money required

Does the case use a normal size PSU, or is it a smaller model? To find this out, pull the side panel off the computer and measure the dimensions of the PSU (height, width, depth). While you're at it, look at the brand and the wattage. If possible, find the sticker on the side or top of it that looks like this, and tell us what it says
