As things were tight at Christmas time I ended up building my 7 year old a PC from components I had squirrel'd away over the years (i'm a horder ) The main spec's were, if I remember correctly: AMD A64 3700 San Diego an SLi capable Foxconn 939 motherboard a reasonable 500w Modular PSU and an old Radeon 800GTO graphics card. Its playing all his basic games like all the LEGO series and stuff like that but he's getting more into his gaming so I got him Batman AA. Unfortunately it comes up saying the CPU isn't fast enough and the graphics card doesn't support the right shader model. My fault for not checking!! Question is, if I OC the CPU up a bit closer to the 3ghz it says it needs (I know it won't reach that though) and say, bought an ATi 5770, does anybody reckon this would run some of these newer games or am I looking at upgrading the lot.
