Journal IF for PhD Applications

[WannaBePh]

Hi All,

I have what I'm guessing is a bit of an odd question. I am applying this round for PhD programs with pretty subpar GPA (~3.1 overall, ~3.3 in major), and relatively high GRE (~90-95% overall). Total of 4.5 years of full time research experience, 2 full time during undergrad, 2.5 by the time of application, plus 2 years as a part time undergrad. Until this past year I had no publications due to switching labs/some of the experience being in an industry setting. Currently I have a first author in review and one about to be submitted in very good journals (both IF ~16), as well as 2 co-authors in top tier journals (CNS sub-journals) and 2 more in lower tier journals, 2 published conference talks, all in the same research area. My question is - how much does the impact of my research matter in the eyes of an admissions committee? I find it somewhat funny that if I had a PhD I could win a post-doc at top 10 institutions but maybe not get accepted to those same institutions as a grad student. 

Thanks for your input.
