I haven't build a gaming pc in quite some time and wanted to ask for some help. I mostly play Overwatch, league of legends, and battlefield 4. I'd prefer to have a monitor as well as a WiFi adapter and or a PCI WiFi card as I mostly play away from a wired connection. Budget is $1000-$1100.
That's a reasonable budget, do you also need the OS?
Also with reguard to WiFi, I never like that for gaming as it tends to add a lot of latency. I'd personally suggest looking at a powerline network solution as that allows you a more stable wired connection without the hassle of running network cables through your house.
As a rough guide I'd suggest for a good value gaming build to look at a Core i5 processor (if you want to save a bit of money the slightly older Haswell 4xxx series parts are just as fast in most games as the newer 6xxx and might cost a bit less- they also use the older but slightly cheaper DDR3 memory).
Make sure to get at least 8gb of ram (16 is better but it's easy to upgrade later and 8 is generally sufficient right now).
Also be sure to invest in a reasonably big SSD as your boot drive, don't go less than 240gb as Windows can get quite bloated over time.
The main thing to invest in is the graphics card. The best options for your budget are probably one of the upcoming new Radeon RX 470 or RX480 cards, which look set to offer massive perf for the price and should be able to max out gaming at 1080p (470) and 1440p (480) respectively. Above that the new GTX 1070 is a hell of a card but also pretty expensive and might be a stretch in your price range. Other good alternatives would be the current nVidia GTX 970 and 980 cards, although again I'd wait until the RX480 launches on the 29th before buying one of those as NV is inevitably going to drop the prices on them given the RX480 is as fast as the 980 for only $200.
