I've recently just bought a new PC. I had my previous one for 5+ years, and while it was still in decent shape and running well, I wanted a proper upgrade. I had to start from scratch, because upgrading from the old parts would have just been pointless because pretty much everything needed an upgrade.
Anyway, here are the specs, for anybody interested:
COOLERMASTER HAF 922 MID TOWER GAMING CASE
Intel® Core™i5-2500k Quad Core (3.30GHz, 6MB Cache) + HD Graphics
ASUS® P8Z68-V LX: USB 3.0, SATA 6GBs, ATI®CrossFireX
8GB KINGSTON HYPER-X GENESIS DUAL-DDR3 1600MHz, X.M.P (2 x 4GB KIT)
2GB NVIDIA GEFORCE GTX 560 Ti - 2 DVI,HDMI,VGA - 3D Vision Ready
Memory - 1stHard Disk
120GB INTEL® 320 SERIES SSD, SATA 3 Gb/s (upto 270MB/sR | 130MB/sW)
CORSAIR 750W ENTHUSIAST SERIES™ TX750 V2-80 PLUS® BRONZE
It's not right at the top of the line, but it's a really nice system. It runs Starcraft 2 on extreme and stays above 100 frames per second. I've yet to try any other games on it. I'll be looking to buy Battlefield 3 on the PC at some point and see what it can do.
Speaking of Battlefield 3, I bought it on 360 and I've played a bit of the multiplayer. It's very different to my usual Call of Duty, and sometimes it can be far too slow for my liking, but on the whole, I really enjoy it. The random stuff you can get up to in the game is really fun, and playing it with a few friends is a laugh. It will take a little while before I get "good" at the game, but I'm enjoying it so far.
