My situation starts like this, my younger brother broke my sweet gaming Pc at home. So he took it into best buy and as they were fixing it they dropped the CPU on the ground (thanks geek squad). They reported to me not only was my CPU fried but my GPU and mother board was too. In this case the manger gave my brother a Compaq Presario SR5350F that includes a 1.8-GHz Intel Pentium Dual-Core E2160 processor and two sticks of 1GB PC2-5300 DDR2 memory (2GB total) mounted on an Asus IPILP-LC motherboard with integrated Intel GMA 950 graphics and I personally added a PCI Express GeForce 8600 GT. What I am trying to do is turn this PC into a good gaming PC and I feel my GPU is good but my CPU is too weak. Would I need to upgrade my CPU and Mother Board or just CPU and what should it be? Plus to note I salvaged a Nosietaker Enermax 485w power supply from my old PC.
The PSU would be what ever came standard with the Comp or a Noisetaker Enermax 485w i can put in... the games i have in mind to play on the system would be Oblivion, Spore, Empire total war, and Half life.
