Thanks for the clarification.

If you are patient andgot some spare time on your hands, you might consider getting a part-time job for a while and wait for the 9900 cards to come out around november.

That's like saying putting two 32bit processors together gives you a 64bit processor (Jaguar?). Things just don't work that way. 256bit is still 256bit sent per clock. When the 8800GTX's are sending 384bits at any one time, it's going to be faster which shows in benchmarks. Disagree that the amount of graphics memory is the bottleneck. The GX2 does have 2x512 compared to the 768MB of the 8800's.
If the 9900's are $700+, I'll buy the 9800GTX in July when the 9900's are released, last I heard.
