I'm thinking of getting a new computer cause my current one is crappy. Can't even play Counter Strike without lagging in 10-player server.
My computer guy said he'll make me a good computer with 7300(and 2 giga and all that good crap) for 800 bucks. However he said he can also give me 7900 and 2-3 gigabyte(Depending on mood) for 1,000+
One day, I shall come back. Yes I shall come back, until then there must be no regrets, no tears, no anxieties...just go forward in all your beliefs and prove to me that I am not mistaken in mine.
GeForce 7900 Series is lot more faster then GeForce 7300 Series. The reason is that GeForce 7900 Series is for designed for "enthusiast" gaming experience.
Regarding RAM:
And 2 GB RAM is more then enough for current gaming and computing needs. Get two 1 GB RAM Sticks and make a "Dual Channel Memory" Setup.
3 GB RAM is not necessary but the choice is yours.
