Apparently, Dell will have a window of about a month before being joined by the competition (Guillemot, ASUS, LeadTek et al) in offering the enhanced board. Dell representatives told Sharky Extreme that their board will carry the 'reference design' tag usually reserved for NVIDIA's designs. This design is being farmed out to other OEMs and thus you can expect to see more 64MB DDR GeForce 256 cards out in the near future.
The 64MB adventure for Dell is certainly a side step from the normal corporate world in which they live. It's firmly aimed at attracting gamers (after all we're the only ones crazy enough to shell out four grand on a PC instead of a steady diet of three meals a day). This new offering from a corporate giant is a far cry from the well-known but relatively small system companies like Alienware and Falcon Northwest accommodating gamers high-end needs. It is certainly a plus for gamers, when a "corporate PC" company allocates a segment that's dedicated to the gaming community. For the first time, Dell will have a heavy presence at E3 with the mission of appealing to gamers with a well-built PC at the ready in one-hand and (we speculate) a souped-up NV15 in the other.
Obviously with NVIDIA's NV15 to be released sometime in the not too distant future (we'll let you in on it soon) this Dell card isn't for everyone. If you already own a 32MB DDR GeForce 256, then it isn't worth the money and the short reward for buying the card. Yes you get faster frame rates at the higher resolutions but in today's games the difference in frame rates could only be obtained under very unusual settings. If you want to eke out a few extra frames per second, try your hand at overclocking. The rewards are there in the form of roughly a 10% gain- and that's just for free.
