So yeah , as you have known that I’ve bought GTA IV and Fallout III . Both are superb games and I’ve finished both of them (Fallout 3 – Good Karma way , skipped some side quests) and GTA IV (Completed main quest + doing side quests). As we all do know that GTA IV is a very demanding game and it requires a lot of CPU power and GPU Power. Nevertheless , I am using a 3 year old Dell Dimension DIM9100 series 😛 , its a Pentium D 830 3.00Ghz , 4GB DDR2 533Mhz RAM , 500GB HDD + GeForce 8600GTS 256MB GDDR3. Well basically all modern games run fine on mine its just that GTA IV is tricky.
