I'm looking at spending no more than $450 for the GPU, CPU, Mobo, and Memory. Right now I'm set on the ATI HD 57xx GPU's. I'm not sure which combos to go with. Also, this is being solely used for gaming, and I will not be utilizing the built in GPU, unless there is some way to hybrid CF with the HD 57xx's that I'm unaware of?

AMD Phenom II X4 955 BE --- $240 (Combo)
ASUS M4A785TD-M EVO AM3 AMD 785G
Patriot G Series "Sector 5" DDR3 1600 2x2GB --- $97
XFX ATI HD 5750 --- $140
--- Total: $477

AMD Athlon II X4 620 --- $180 (Combo)
ASUS M4A785TD-M EVO AM3 AMD 785G
Patriot G Series "Sector 5" DDR3 1600 2x2GB --- $97
XFX ATI HD 5750 --- $140
--- Total: $417

AMD Athlon II X4 620 --- $180 (Combo)
ASUS M4A785TD-M EVO AM3 AMD 785G
Patriot G Series "Sector 5" DDR3 1600 2x2GB --- $97
XFX ATI HD 5770 --- $180
--- Total: $457

Would I see better performance out of a Phenom build with the HD 5750 or an Athlon build with an HD 5770?
Is the Phenom worth $60 more than the Athlon?
Will either of these processors take advantage of the faster DDR3 memory or should I get DDR2? Or even DDR3 1066 for $10 less?
Is the motherboard with the build in GPU worth the money, or should I opt for a cheaper AM3 motherboard without a built in GPU?

Any advice is appreciated. I'm not sure how the memory speed syncs up or gets bottlenecked by the processor speed. I'm trying to get the best system I can for the least amount of money.

Thanks in advance.

Anywhere but there
If this is for gaming only you might look into the 720BE X3, which is just a Phenom with one core disabled. Most games won't use all four cores and you might save a little money. The 720BE will be as good or better than the X4 AII in games and, for most games today, will be as good as the X4 Phenom. The exception is the rare game that will actually use all four cores (very short list right now). Any on-line game will not use four cores.


Generally, DDR3-1333 RAM with tight timings (like CAS 7) is better then DDR3-1600 with loose timings.

You won't see much of a difference in performance between DDR3-1333 and DDR3-1600 but the DDR3-1600 will allow more play room if you're overclocking. It also costs more if you get tight timings.


Whether you get DDR2 or DDR3 will depend on your motherboard choice. AM3 CPU's can run in either AM2+ (DDR2) or AM3 (DDR3) motherboards but the RAM is limited to the board.


Built-in graphics are actually less expensive than the high-end chipset without graphics. The 790X and 790FX chipsets are both very good and typically cost as much (790X) or more (790FX) than the 790GX or 785GX (the newer version of the 790GX), which have built-in graphics ...

Processor won't affect you unless you love to multitask. I personally play games while chatting/running pandora or grooveshark/etc. So for me the 4th core is important. If you don't however, you certainly won't be limited by not having a 4th core as QuietIce suggested. And having ddr3 1600 isn't necessary if you can save by going with 1333. ddr2 and ddr3 are about the same price form what I've seen, so it depends on what your mobo supports. Also, I would personally prefer a nvidia 260gtx over a 5770, but that might just be me. I got mine for $174.99 I believe a few weeks ago.

I'm still on the fence about the AII vs the PII. Thinking about possibly getting the AII with a 5750 and in a few months grabbing a second 5750. 5750 CF is pretty amazing, and only 280$. I'm an ATI/AMD fan, so an nVidia is out of the question, especially considering the 5xxx ATI's are superior cards.

That's really quite debatable.

Well it depends on the game. In ultra high setting games, the 5770 runs along side of the GTX260-216, while the 5750 runs just ahead of the GTS250. And in less demanding games the 5770 runs along side the GTX275 while the 5750 runs hand in hand with the GTX260-216.

When you go into CF/SLI reviews, the 5750/5770 pick up a lot more benefit from the second card than the GTX260/275's do. Two 5750's performs better than one GTX295, for only $280.

Also, the 5770 is about $20 less than the GTX260-216 and atleast $100 less than the GTX275. With the 5750 being $40 less than the 5770.

IMO, there is no comparison. Especially when you add in Eyefinity and DX11 compatibility.
