Alright, I need instruction because I'm just recently getting into computer systems and I need to know what I'm doing.

I bought an Acer Aspire T180 and it has mostly everything I need for Crysis, except a video card. The minimum for the game is an Nvidia 6200 or ATI X1300 - Shader Model 2.0 and what I've got is an Nvidia GeForce 6100 with an nForce 430 MCP graphics solution. The 6100 is apparently capable of Shader 2.0.

Question: Despite the fact that I'm upgrading to an Nvidia 7600, would I be capable of playing the game without it?

Also, can I even upgrade my card, or is it part of the motherboard (intergrated nForce thing?)?
