I have an older configuration PC with Core 2 Du0 E7500@2.93GHz. It has got a DDR2 Corsair RAM of 4 GB sitting on a DG41RQ mother board. I have recently installed a GEFORCE 610 GT 2GB@DDR3 GPU. I am running Ubuntu 13.04 with the Noveau driver. It has been running DOTA 2 at all min settings. I want to play DOTA 2 at best quality from whatever this configuration can permit. My budget is around 10000 INR and suggest which component should I upgrade.
Note: the Mother board has only one PCI E slot which is occupied by the GT 610
