Consider getting minimum 1 GB of RAM or better, 2 GB of RAM. Prices have dropped drastically, so it's worth it. Hmm. Since you do not want to game at insanely high resolutions etc, an E4300, 1 GB of RAM, and an 8600 GT would be enough for you.
the gpu sell for about 8.5k , there are e lcd models from view sonic selling at 10.5 k to 11.5 k . and please mention a budget that would help you suggesting better.
