Hello all! I'm new to all this so please be a little easy on me! I'm looking to buy a new gaming computer and was looking for some help. I want to spend from $800-$1,000. $1,200 fully ready to play with monitor, key board, mouse, and speakers. Any ideas? Any input would be appreciated! Thank you for your time!

I'm about to purchase a new computer and I wanted to know how smooth it would run Arma 2 and Operation Arrowhead. I'm looking for quality graphics, but I want the game to run well and not lag. I'm new here so any help goes a long way! Thanks! What I'm looking at: Windows 7 Home Premium, 64 bit Intel Core i7-860 (8Mb Cache 2.80Ghz) 4 Gb Duel Channel DDR3 SDRAM at 1333Mhz-4 DIMMs Ati Radeon HD 5770 1024Mb GDDR5 500Gb-7200Rpm, SATA 3.0Gb/s, 16Mb Cache 16x Dvd+/-RW Drive On a 20" Dell ST2010 HD
