where in the hell can i buy the above metioned cpu? i have looked on ebay, the egg, tiger, im just outta options. any help would greatly be apprechiated. thanks in advance, nick i7 620m
I dont think you'll be seeing this cpu for quite a while at stores as for the main reason is that manufactures like dell, hp, toshiba, ect will get them first. There were never meant to sold on the mass market.
Second, you'll need a new laptop that that can use it. If your current laptop has the core 2's in it. it wont work.
Well guys to help answer the first question: some international eBay listings have emerged (china & uk) for QS (qualification sample) i7-620m's for around $300. These work just like the retail version but consider them the equivalent to a final Beta prior to release.
As for "upgrading" to a dual core, the speed argument has already been discussed in good detail. The 620m will do better in single & dual core activities (ex: games) while the quad core 720 will outperform in multi-threaded apps like video / photo editing & encoding.
One big thing not discussed was the thermal heat factor! The quad core mobile i7's (720) are notorious for running extra hot even in the best designed laptops (search Macbook Pro i7 for a ton of complaints about super hot heat). The dual core i7's (620 & 640m) run a lot cooler.
I'd go with a i7-640m if you want the best dual core mobile processor on the market! Just make sure you use some high quality thermal compound (arctic silver or TC diamond) when you stick the CPU fan back on. Laptop upgrades aren't for the timid so youtube some clips because I'm sure a lot of Alienware laptops are easily upgradable.
Good luck and don't get suckered by the quad-core hype unless you are in video / photo editing & production.
