My computer is quite substandard, and it seldom is sufficient in suiting my gaming needs. I can play sims 2, silkroad online, and warcraft 3 - yet my thrist for playing/obtaining great PC games has not been quenched.

 Recently a friend of mine has searched for a new graphic card for me, his search yielded poor results.. or more unfavourable ones anyways. I learned that Dells are rarely compatible with good graphic cards - they just don't fit. I can't play oblivion, dark messiah of might and magic,etc. How ever i would thoroughly enjoy doing so.

 My tower is a Dell Demsension 4600 and any help/tips would be so gratefully apreciated. Keep in mind that and I am only willing to spend up to $250-canadian on this graphic card, my savings being only at $550ish.
