My immediate reaction is that you've gone from having everything on one home page to being split up into various different sections which I have to waste time going between if I want to access everything I did before...
We had news, sales, reviews, and all the community stuff, including hot topics and my recent stuff (which needs to be put back on the left side of the forum like it used to be), on one page, and you could easily access everything.
So basically it's gone from being streamlined to a convoluted mess.
EDIT: Reading back it sounds overly negative, so I thought I'd add some positives. I actually quite like the new look of the site, and it's much kinder on my ancient laptop than the old site was, so that's good. It's the content issues that are the most pressing.
