When should i take TOEFL , if am writing GRE by September second week or so?

Hi and welcome to my blog,
I opened this blog to help anyone who is preparing for his GRE exam.
I remember myself when I started - I was so lost and in such a panic.
Luckily I got this great Gre guide that helped me a lot
So study hard and good luck!
Am planning to write GRE by September 14th, so when should i take TOEFL? My aim is to join the course that is starting on next September(Sept 2010). Currently am doing my final year in ECE and have done some research project also done some research paper work in the field of VLSI, so what is my chance in getting addmision abroad,mainly US(Top Universities) and Singapore(NANYANG TECH.)? Then, sorry to ask!! If am preparing for the next two month to write GRE and TOEFL, will this give me a good score?
So am in a confused state! , paying this much for two exams and two months to study!! Please reply as soon as possible.
If you plan to enroll for Fall 2010 for a M.S. program in an U.S. university, you may take the TOEFL Nov or Dec 2009. TOEFL doesn’t require as much preparation as GRE.
