Hello, and thanks for reading and helping me with your knowledge. I am intrested in recording games such as Mw2 and BFBC2 using Fraps. At this moment im getting a fairly good record speed at 35-45fps (using fraps) on my rig which is 2gb of ddr2 ram, 2x ATI radion 4850 video cards (512mb) and an AMD Athlon 64 X2 Duel Core Processor 5200 + 2.70 GHz. Tell me what i should improve to get better results, I think adding two more 1gb ram sticks as i have 2 extra slots. Clearly people here have more exp with computers as me, as im 14 but any advise would be very helpful.

Thanks
