There are two new HP laptops available and I can't figure out which one is better. One (dv6985se) is on sale for $850 and has 4GB RAM but no dedicated video. The other (dv6885se) costs $1150 and has 3GB RAM but has a dedicated NVIDIA video card. Is it more important to have the RAM or the dedicated video. And is getting a 64bit computer right now going to have compatibility issues? Thanks! Here are links to the items. http://www.bestbuy.com/site/olspage.jsp?skuId=8893085&productCategoryId=abcat0502003&type=product&tab=2&id=1211587729621#productdetail http://www.bestbuy.com/site/olspage.jsp?skuId=8779404&productCategoryId=abcat0502003&type=product&tab=2&id=1204332257046#productdetail
