Whoa... nasha, those prices are wrong, its more like 1,300 for the FX-57 and 1,100 for the 4800+ X2!
Watermelon, if you DO NOT have a budget, then take into account the PC I want to build and add or subtract parts. Mind you, this PC costs well above 4,000 US Dollars at this point, so take what parts off you feel necessary.
Or, if you are on a tighter budget then 4,500 USD, what is your budget? I can make a parts list invoice for you to order from newegg.com. This way, you will get the BEST POSSIBLE PARTS for the budget you are on. So, what is it?
