The funny thing with Technology is theres ALWAYS something new about to come out. ALWAYS. So i'll be the one to say screw that and think about what you need it for. Gaming you say? You'll want a decent nVidia graphics card and a mediocre to decent processor. If you got an i7 - hell, an i5 to make it interesting - and waited for the new graphics card, hands down the graphics card will be the bottleneck first. It always is, games don't often use all that much processing power. I can understand waiting for a new graphics card - if only to make the price of the current range halve - but personally, I wouldn't worry too much about getting the latest and greatest in processing speed.
No experience with that company but I will say avoid Dell (including Alienware), Hewlett Packard and Apple (duh). Had surprisingly good experience with eMachines, but sadly they seem to be pretty behind with the times now. Got one downstairs that's been running fine for 10+ years now, no upgrades. Was a great backup machine until my parents decided to ditch it's internet connection :/ Anyway, you will always get a better deal building it yourself. If you don't want to dabble with that, look on eBay. Private PC nerds build computers - custom quite often - test them, and then ship them for maybe a +50% mark up. That'd still probably shave a fair amount off the price of most manufacturers.
