The extra 100mhz of the T9300 will probably not be noticeable and certainly not worth the extra money. Are you open to other companies to buy from and if so, what is your price range? Dell hasn't updated the XPS very much and there are newer technologies out (ie faster RAM and better graphics cards).
Well my price range is around 1.5k, and i want a company that i can trust. I hav heard that companys like ibuypower, cyberpowerpc etc. r not reliable.
Yeah, I didn't realize that Dell had dropped the price of the M1730 so much. The last time I saw, that configuration would have run you about 2K. And yeah, I don't trust ibuypower or cyberpower at all. Hence why I bought a Sager.
