I bought this sony vaio serie SV, its brilliant to play games like max payne 3, crysis 2, saints row and wolfenstein on high settings. I already loved this HD laptop. My system is intel core i5 2450m 2.50Ghz turbo boast 3.10Ghz processor, 6Gb SDRAM Ram, 2Gb AMD radeon HD 7650m, 650Gb Hard drive, Blu ray player, Window 7 Home Premium. Run most games perfectly smooth and I upgrade my SDRAM Ram 6GB to 16Gb for 55 quid so all together cost 735 quid. I would say buy this sony vaio instead pay expensive alienware both are nearly same. Also keyboard are showing white neon light under buttons and its very nice laptop.
