you can get a used 4850 for about $50
resolution at the moment is 1024x768 on an old 17" lcd. Looking to spend 75-100 US. No brand preference. Aiming for it to play BF:BC2. I understand at my budget and with the CPU I have I will be playing at lowered detail.
The CPU also has a potential to become popular among computer enthusiasts due to its unlocking potential. Early reports indicate that at least some 210e microprocessors are based on Propus core, and have two cores locked.
The unlocked processor has four operational cores, but no L3 cache, and is identified by BIOS as "AMD Phenom(tm) II X4 910e Processor".
Get a LCD with a better resolution. Most modern gpus are a overkill at that resolution
I recammend if your motherboard has it, you try unlocking the extra 2 hidden/locked "cores" your CPU might have, and cashe.
so: ACC, core unlock switch, whatever's supported on your motherboard.
See if you got lucky and can unlock cashe/extra cores.
As other posters have said your GPU might be held back abit by your CPU, unlocking extra cores/shaders could go a far way to improveing that. That said, even if you cant, atleast overclock the hell out of it.
