M/B is important in the selection of gfx card. I am not a gamer but I have read Radeon HD5970 may be good for your gaming experience if your M/B supports it. I know some older M/Bs cannot run Radeon HD5xxx cards. These cards have 1 GB or more dedicated RAM onboard. You can install another 1 GB of RAM. But that may not bring you much. Around 3.5 GB is usable in a system with 4 GB RAM installed (32-bit OS).

Hope the info is useful.

Look into your M/B manual to see if it supports PCIe 2.0 x16 spec. Older M/Bs support PCIe 1.0 x16. PCIe 1.0 spec is said not to comply with new Radeon HD5xxx gfx cards.

Also check your RAM slots on the M/B, the capacity each RAM slot may hold (e.g. 1 GB RAM stick, 2 GB RAM stick, 4 GB RAM stick, etc.), and your RAM sticks to see if you can add more RAM.

The way the memory issue was explained to me is that 32bit
Windows can only access a maximum of 4Gb because the term
'32bit' essentially refers to the number of memory locations that
can be accessed, ie 2^32 = 4.294 billion ie 4Gb. The actual
maximum is also reduced by the OS itself & in most cases,
even if 4Gb is actually installed, only approx.3.2Gb will be
available for programs. The only way have more available RAM
is to use 64bit Windows.

johnr: The actual maximum is also reduced by the OS itself
Not quite true. It's reduced by the need to use your hardware.

Also, it's not that modern processors can't handle more RAM, it's just that MS has decided to make some changes to Windows, and they're using this memory limit to force people to accept the changes.
