Can you take a look at this

What are you planning to use it for? Whats the resolution of your current monitor? And what is the max budget you are willing to spend?

I see with the mail in rebate the price comes down to $105 + shipping. Over at newegg, an Asus 4770 can be had for $109, but gives you a free game. The radeon 4770 will also save you money over the life of the card due to decreased power usage... and will also outperform the nvidia 250 in many instances. The only other recomendation I could make is to consider a motherboard that supports 2 PCIe x 16 video cards instead of one as it is always nice to be able to easily upgrade should the need arise?!

No, only nvidia chipsets and X58 chipsets are SLI capable because nVidia licenses SLI. ATI cards currently provide you considerably better bang for your buck and allows you to use basically any chipset so you may want to consider an ATI card.

hmm does seem like ati would be a better choice, It would probably be wise for me to go with this http://www.newegg.com/Product/Prod [...] 6814141098 and when i want to upgrade later on down the road pick up another one of them, am i right?

ASUS has much better warranty for the same price. XFX has a lifetime warranty on all ther cards! Try to take this into consideration as parts do burn out and it really sucks when the item is just out of warranty and you have to fork over more money for a replacement. The good thing about SLI and Crossfire is that if one video card dies, you can still play with the remaining functional card until you get the bad one fixed or replaced. In a non-sli/crossfire system, when the video card craps itself...you are dead in the water.

unless your case is quite small then there is no advantage to modular psu's . The hx 620 is a good but very expensive . A corsair 650 TX is $80

Socket 775 is intels old platform and being phased out .

Consider building an AMD am3 computer .
It will be cheaper and more future proof

Currently the 720 be is $119 and out performs an e8400 in games and is a better multitasker thanks to having 3 core instead of 2

2 x2 gig of good low latency DDR3 ram is $65

SUS M4A78T-E AM3 AMD 790GX HDMI ATX $125

Upgradeable , future proof , cheaper and better than an e8400

I didn't want to say it, but I agree with the outlander. You can get a 3.1 Ghz amd callisto processor with an Asrock crossfire capable motherboard (Both are the new AM3 technology), for $183... just look under combo deals at the Asrock 780g motherboard. The 780gx model Asrock costs more and does not appear to perform as well. You also have the possibility of unlocking the other two cores on this cpu.
