i recently bought a pc to game on but found the description to what i actually bought was nowhere near. i have the intel DQ965GF motherboard with intel pentium d 2.8ghz cpu and basic intel fan. my gaming card is the amd radeon 5450 and i only have 4x1gbram (ddr2) got a feeling i will need to get a new motherboard and upgrade to high specs in the future but for now what could i possibly use on my system to boost it up so im able to actually game at a good level. also what is compatible with my motherboard.
