Decided I needed some knowledgeable feedback about building a new gaming desktop since I have little know-how when it comes to customizing my own. I tried going through the past week or so of threads to see if anything matched (I'm sure I missed something), but all I could find were either higher budget rigs or someone that was upgrading and knew how to install the parts/assemble their own.
I'd like to have a desktop that can play a lot of the modern games on higher settings (not necessarily max/ultra). I have no idea how to physically put a new computer together or install upgrades, so I'm looking for a new premade tower (I have the monitor/keyboard/mouse/headset/etc.).
It's also very unlikely that I'll ever get into overclocking, and if I recall correctly that would mean I could go cheaper for certain parts. I'll also need a new OS, preferably staying with windows 7 as I've heard that 8 is having some software compatibility issues. The games I currently play are Skyrim, WoW, GW2, and Boarderlands 2 - and likely trying ESO when it drops. So I'm looking for something that'll run those on higher(est) settings, I'm not aiming for something that can run Far Cry 3 on max/ultra.
I'm giving my current tower to my brother, so nothing from it can be reused. I'm located in the Northeastern US.
Budget - As low as possible, but preferably no more than $800 ($900 if really wanted to upgrade 1 or 2 things in particular because they're that much better).
Other Info: It'll have to be wireless, as I have no cable availability for internet - I do have a cheap USB wireless card though. My current desktop runs WoW at 20 fps in empty zones/space and it comes to a standstill during lust/hero when 40 people are attacking Sha.
I don't care if the tower looks like some futuristic spaceship; I'd much rather it be functional and have solid dust filters/ventilation. Although I wouldn't complain if it looked good as well. Other than that, I'm open to just about any and every suggestion.
Sorry for the wall of text, and thanks in advance for any assistance.
