I5 2500k Gaming Build

I would look hard at a single GTX570 for about $290 as a compromise...you can add another later if/when you want more speed, SLI seems to have fewer issues than Crossfire according to most.

Here's a few ideas for a dual gtx 560ti set up. That board down below is a 16+2 phase board which will give you a nice steady and high o/c.

http://www.tomshardware.com/reviews/geforce-gtx-560-amp... <----- you want the ti gtx 560, not just the 560 which is a total different card.

BUY FROM AMAZON! NO TAXES!!!!

I would only buy ram & cpu combo that why_me posted and the psu- the one why_me posted from newegg since they are such great deals

i would buy the cpu cooler from frys too since it is cheaper

to make it easier for the op to find here is the dvd burner- http://www.amazon.com/gp/offer-listing/B003MRHOQG/ref=d... get the one from amazon

get this motherboard- http://www.amazon.com/Gigabyte-Intel-Express-Motherboar... save even more because there is no taxes this motherboard will go out of stock because it is priced about 20$ less for a new one that has 1 more feature that gamers will not use

you can get that evga gtx 560 ti for the same price at amazon

here is a evga gtx 560 ti ds- http://www.amazon.com/EVGA-Superclocked-PCI-Express-Gra... it is cheaper than the twin frozr II at newegg because there is no taxes. it is clocked higher by about 80mhz and has comparable cooling

there is also this card which is pretty awesome it is faster than the gtx 580 (not as fast as 2 560 ti's) but you cant sli it in the future- http://www.amazon.com/EVGA-GeForce-PCI-Express-Graphics...

you may want a nicer case- http://www.newegg.com/Product/Product.aspx?Item=N82E168...(Computer+Cases+-+ATX+Form)-_-Rosewill-_-11147107 108$ after taxes (im from ca too)

or a little pricier- http://www.amazon.com/SILVERSTONE-RV02B-W-Steel-Tower-C...

http://articles.latimes.com/2011/jun/30/business/la-fi-... <----- California passed a new tax law for Amazon that's already in affect....so they pay taxes on all Amazon items now.

i knew that it was passed.....i just bought books from amazon (with school starting again ughh), no taxes. they havent started enforcing it yet obviously. when they do amazon says they will stop selling to california because that is what gives them an advantage in sales.
edit: just bought something from amazon (the vendor) no taxes.

you posted this twice close the other one...

Just a couple of comments:
1) Make sure if you get the 560 cards, its the 560Ti not just the 560.
2) I agree with the first post, if you can stretch for a single 570, go for that. It will still run all current games on maxed settings. And will allow for another to be added in SLI in the future for even better performance.

Generally if your making a new build, its best not to buy SLI straight away but buy a single card, leaving headroom for an improved build when required a year or 2 down the line.
