RAM comparison

hi i am looking at two seemingly similar memory sticks:

1) (Model: CGM2X2G800 G) http://www.bestbuy.com/site/olspage.jsp?skuId=8724847&st=corsair+memory&lp=2&type=product&cp=1&id=1200703058743

2) http://www.newegg.com/Product/Product.aspx?Item=N82E16820145184&nm_mc=OTC-RSS&cm_mmc=OTC-RSS-_-Desktop%20Memory-_-Corsair%20(XMS%20Series)-_-N82E16820145184

can someone tell me why the huge price discrepancy?  how are they different technically?  and lastly, i have a HP Pavillion 1630n that uses this: Memory (DDR2-800MHz Dual Channel SDRAM), can either one of the above RAM be used in this computer?  thanks.

You can go ahead and pay more for the DDR2-800MHz if you want and it should work with your system, but your PC won't run the memory any faster than 533MHz.

You should just save the money and buy the DDR2-533MHz as per the RAM manufacturer's website (www.corsair.com).
