Newegg has earn a very good reputation and is good to trust. They have daily rebates, and promos that you can take advantage of. They also have a great customer service. I pick them above other websites when of computer hardware it comes.
The Twin Frost (more expensive) has a factory Overclock that will make the card go faster WITHOUT stressing it at all, keeping the temps, consumptions and lifespan the same but making it go faster.
Also the Twin Frost has a better cooling option, which I recommend.
The fancy blue and black themed one, Twin Frozr 4, is a power edition meaning you can overvolt your core memory and vddci for better overclocks. It also features propeller blades which means they spin the wrong way for 30 seconds when you start your system to get rid of dust then spins properly, if you can, get the Twin Frozr 4(blue black) one. New Egg is VERY trust worthy.
newegg has the best deals anywhere i promise you ive looked. the only thing that sucks is the mail in rebates you have to wait atleast 6 weeks to receive your visa gift card rebate but atleast you can use it anywhere.
I've noticed with most rebates on Newegg recently (e.g., Gigabyte and MSI), I've had the option to go the usual route and get the full rebate, but it will take 8 to 12 weeks, or I can get the expedited rebate in 2 to 3 weeks if I give up 5% to 10% of the rebate for "express" handling. For instance, my last rebate was $100 from MSI (bought a laptop), and I chose the expedited rebate and got a Visa card for $91 in only 2 weeks. I thought it was worth it because after ten or twelve weeks I would have completely forgotten about the rebate and wouldn't have noticed if it had never come.
Yes Newegg is great in my opinion. When I did my December 2010 build I had about $300 worth of rebates coming back. I choose the expedited option and got them in about 2 weeks end up getting about $290 combined not to bad for a 2 week wait instead of 6 to 8 weeks.
