I currently have a Dell Inspiron E1505 with these specs: 1.83 GHz Core Duo T2400 with 2 mb cache 1.5 GB ddr2 ram intel 945gm integrate graphics with 256 max memory. This configuration is crap for modern games, basically the integrated graphics fault. But I have seen a deal for a Sony VAIO with these specs: 2.26 GHz Core 2 Duo with 2 mb cache 4GB RAM ATi Mobility Radeon HD 4650 with 512 mb dedicated memory and 1.6 gb intel integrated for 2 gb of graphic memory It costs 649, and is it a good configuration for games? Is it worth the upgrade? Internet benchmarks show that the 4650 mobility gpu I fairly good for games.
