I just got a new Alienware X51 R2 and was wondering which actually is better in terms for Gaming.. i usually play MW3 & Battlefield 4 which i could not play on my old PC that i built... so it's the Alienware X51 vs My Build.. The specs: AMD Phenom(tm) 8450 Triple-core Processor 2.10 GHz, 2.00 GB OCZ DDR2 Fatality Edition RAM, NVIDIA GeForce 9800 GT 1024MB, XFX 750a SLI nFORCE Motherboard, WD Raptor 36GB 10,000 RPM x 2 WD 80GB x 1 Running Windows XP Professional Version 2008 Service Pack 3 Any Advice would be great.. thanks
