Should I upgrade my RAM?
I have 512mb of PC3200 RAM and a 6600LE.
My PC can play Doom 3 on high settings fine except when I open doors, then it lags for about a second.
To me this appears to be a loading problem, do I have enough RAM?
If not there is a sale at PC World where I can get a stick of PC3200 512mb Ram for just £25. Should I upgrade?
Or do you think it's my graphics card?
Intel Core 2 Duo E8400 @ 3.7GHz
4GB OCZ PC-6400 RAM
Samsung Spinpoint 1TB HDD
ATI Radeon HD4890 with VoltageTweak
OCZ Stealth XStream 600w PSU
