Hi at the moment i'm running Call of Duty 4 on low quality and im still lagging. Here are my specs: 1.Dual Core 2.00 GHz intel Pentium E2180 (Pentium 4) 2. PCI express port for GPU 3. A dell 0RY007 Motherboard 4. 2 RAM's each 1024 MB (4 slots in total) 332.5 DRAM frequency 5. An ATI FireGL V3100 128MB graphics card 6. Not sure about watts and power 7. My core speed on the processor keeps changing from 1195 to 1995 (?) on CPU-Z My budget is between 50 and 100 canadian dollars. I live in Canada. I want this new graphics card to allow to me play medium quailty at least with minimal to no lag. Thanks ahead of time!
