Building a new PC, unsure on motherboard

I'm building a new computer (for regular gaming, nothing extreme), and am, among other things, unsure on my choice of motherboard. I want to use the Pentium D 805 and overclock to at most 3.8 ghz. Which brings up my first concern. The article praising the 805's overclocking is almost 2 years old, will it still be good enough for most games, and is there a better value for a processor? Now I want to use 2-4 gigs of pc2-6400 ram, http://www.compusa.com/products/product_info.asp?product_code=3,46831&cm_ven=dealm_site&cm_cat=deals3_2007&cm_pla=site&cm_ite=dealmac, so four ram slots (and pc2-6400 compatibility) would be necessary. I will be using my 8600 GT until I can buy a new card, so a PCI-e slot needed. The motherboard I found is an eVGA 650i Ultra, http://www.newegg.com/Product/Product.aspx?Item=N82E16813188017&Tpk=eVGA%2b650i%2bUltra.
Can that board overclock it to 3.8? Now, if there are any better-priced components that fit into my scheme, what would they be?
