My friend bought a new upgrade kit for $159.99, a budget asusrock micro atx with a geforce7050 chipset, two 1 gb sticks of cheap generic ddr2-800, a retail regor 250 with its tiny cooler. A 500 gig seagate 12 series sata 2 hdd was $49.99. He has a xbox360 with lots of xbox360 games so there is no point in upgrading the video. He wanted a fast computer for media/movies/internet which the geforce 7 does quite well. Also reusing a case/300 watt atx, ide dvd burner and usb2 external hdd.
The board sets the 1.4v chip at 1.429v to compensate for vdroop since a .3v vdroop under load which is typical for a poor p/s and cheap board. I dropped the HT to 800, mem to 667, enabled a fixed speed setting that makes the pci and pcie buss stay at stock. 3.59ghz(242fsb) brought the memory back up to 398mhz(796mhz effective). the HT back up to about 940. Overclocked at 3.59ghz even under load the cpu stayed the whole time under 37 C with 34-35C being the average temp. It also runs really quiet all the time.
The regor 260 gives you a higher multi for a stock 3.2ghz clock, so add .59 and you get 3.79ghz with a cheap board/mem that comes packaged with a budget upgrade kit.
Keep in mind on most cheaper boards the northbridge,memory,ht,sound chip,lan chip,and sometimes the gpu, also gets overclocked with the fsb, so with a 242fsb speed it proved to be stable but at 248 it had sound glitches when tested playing the pro street demo. It was a bit choppy, the geforce7 is about the same speed as the old ati 9600xt or geforce5900 so games like call of duty play ok on it.
The regor is really fast for a budget chip, It would do ok paired with a card like the 5770 making a cheap and quiet running gaming system.
