First time building a gaming pc. This is what i put together on newegg: Optical Drive: ASUS DRW-24B1ST/BLK/B/AS Black SATA 24X DVD Burner - Bulk - OEM Graphics Card: XFX HD-687A-ZNFC Radeon HD 6870 1GB 256-bit DDR5 Case: Rosewill CHALLENGER Black Gaming ATX Mid Tower Computer Case Power Supply: Antec EarthWatts EA-650 GREEN 650W ATX12V v2.3 SLI Ready CrossFire Certified 80 PLUS BRONZE Certified CPU: Intel Core i5-2500K Sandy Bridge 3.3GHz (3.7GHz Turbo Boost) LGA 1155 95W Quad-Core Desktop Processor Harddrive: Seagate Barracuda ST31000524AS 1TB 7200 RPM SATA 6.0Gb/s 3.5" Internal Hard Drive RAM: G.SKILL Ripjaws X Series 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model F3- Motherboard: MSI P67A-C43 (B3) LGA 1155 Intel P67 SATA 6Gb/s USB 3.0 ATX Intel Motherboard Total: 700$. After RMA: 650$, I saved 50$ because those last six parts were part of this bundle. So, is this any good? i just want some confirmation before i buy. Will this run games at mid-high settings on 1920x1200 and last a couple years?
