I am writing GMAT in a few days to apply for an MBA for Fall 08. I have a MS in Computer Science but desperate to get out of my current IT job & relocate to Boston or NY. I think i'll score 650 on the GMAT. It is my understanding that if I score over 700+, I have a good chance in schools ranked #15 to #25 (leave aside other admission factors). With 650, I might have a good chance in schools ranked #26 to #40.
Alongside, usnews.com states that salary grade falls near $100K for people from #15 to #25 but abt $75K from #26+.
It's a rough estimate... I am already near the $70K mark. So should I apply for 2008 if I get 650 OR rewrite and apply for 2009 ?

Personally, I don't think I'll get more time to prepare on a 2nd attempt & quite unlikely that I'll cross 700 in the 2nd try. I am pretty desperate to get into a program & switch my career at the earliest but I'm told that if I don't do an mba from a high ranking school, i am just wasting my time.

Need some solid advice.
