Planning a system upgrade

My system is starting to show its age and with Black Friday approaching, I am looking into ways to price effectively upgrade so I can jump on a good offer. I have read through several other system building and upgrading topics, but still have some questions I hope to resolve.

My computer is primarily used for gaming although I also use it for light office work such as working with Excel and various development IDE's. I play a variety of games such as StarCraft 2, Fallout: New Vegas, and Dragon Age: Origins. I would like to stay around $500 for the upgrade, but am flexible within reason. I don't favor any one brand over another and all parts will be bought and delivered within the United States. Based on what I have read in similar threads, I have modified the parts I am looking at. I am not planning to overclock and I game at 1440x900 resolution.

My current system is a Core 2 Duo E6600 from which I would like to keep my case, 550 watt power supply, DVD burner, 300 Gig SATA 3.0Gb/s HHD, monitor, and Radeon HD5770.

Currently, I am considering the AMD Phenom II x4 955 along with the ASRock 870 AM3 motherboard, G.Skill 4GB DDR3 1333 RAM kit, and a second HD5770 to run CrossFire. I would also like to pick up something along the lines of the Crucial 64GB RealSSD to use as a boot drive if I can find a good deal. Lastly, I plan to buy an OEM copy of Windows 7 Home Premium.

Since I have never used it or known anyone personally who has, my questions really revolve around CrossFire. I have poked around for information, but still remain anxious of how such a build would turn out.

From what I understand, two cards each running at x8 rather than both running at x16 is not something I should worry about. Is this really the case or do I need to dig deeper for a more appropriate motherboard? Would one card running at x16 and one card running at x4 be better, worse, or the same?

Judging from the benchmarks I have seen in various places, the performance improvement from CrossFire should be noticeable. However, benchmarks are not too handy in the real world and some people seem to have problems when running cards in CrossFire mode. Are the drivers really ready for prime time or do only certain games properly support CrossFire? Will CrossFire actually improve gaming considerably? By that I mean can I expect consistently higher FPS without significantly more heat and noise being generated inside the case?

Currently, my system bogs down tremendously in StarCraft 2 custom games when hundreds of units appear on screen even when settings are reduced to low. I realize such custom games are taxing on any system, but would there be a noticeable improvement after the upgrades above?

Any feedback on the components or more information on CrossFire would be appreciated. Thanks!

At 1440x900 a 5770 is plenty of horsepower. I wouldn't even bother with crossfire or a GPU upgrade. However, you are correct that x8/x8 crossfire is fine, and I'd sooner run x8/x8 than x16/x4.

Your CPU and mobo upgrades sound good, I'm guessing your current mobo is running on DDR2 preventing you from carrying that over? And for about the same price I would go with this ram. Costs you $4 more but I think the lower voltage required is better in the long run.

If you really have your heart set on crossfire, do all the other upgrades first and then see if you still feel the need for it. Dragon Age and SC2 are two games that see a lot of benefit from quad core vs dual core so that should be of substantial benefit to you.

I agree with darke, don't bother with CF for 1440x900. That $130 is better put toward getting the SSD today (though personally I'd get a Sandforce over a C300).

How much DDR2 RAM do you currently have? If it's 4GB, there is no reason not to carry it over into this build. You need to swap your mobo choice for a DDR2 board like this one though.

The A-DATA sandforce is a bit cheeper that the OCZ one. Not sure if there is any performance difference though :confused:

Thank you all for the input.

The advice of lower voltage RAM and trying a new processor first sounds good and I think I will go that route. The write speed on the Sandforce certainly is more attractive than the one I was looking at. I forgot to take into account the cache/swap files which I assume would be on the SSD along with the OS, so write speed would still important. Do you have any idea when SATA 6.0 G/s drives with decent write speed will be available?

My current system has 4GB (4 x 1) of DDR2 533 Kingston ValueRAM. Is the improvement of going to 1333 DDR3 not worth $65? I already scaled back the RAM from DDR3 1666 and the CPU from a 965 based on information in similar posts and am hesitant to scale all the way back to DDR2 533.
