One of two CPU/GPU Combinations... help? :D

post #1 of 13
Thread Starter 
Well I decided it's I upgrade, and get a new system. I just need one more uncertainty addressed.

I can go with one of two CPU/GPU combinations (availability isn't so high where I live, and I cannot order off the internet :/):

1) Core i5-2500K + AMD Radeon 6790

2) AMD Phenom II 1100T + AMD Radeon 6870

The system will be used primarily for gaming, software development (C++/C#/Java), and video processing. Mainly gaming tho.

My opinion: the second combo seems more appealing, as the GPU is the bottleneck in nearly all games, the pure awesomeness of sandy bridge is making me hesitate tho :/.

Oh also, gaming @ 1440x900, would you possibly know what FPS I would expect in the most demanding games (Metro 2033/etc etc)? EDIT: I should explain that I've read many reviews regarding the 6870 and the 6790, but they're all with i7's and stuff. So I'm not sure if it will differ with the lesser 1100T CPU.

I appreciate any replies! thanks!

EDIT2: I'm sorry if this is the wrong section :S.

the sandy bridge i5-2500k CPUs are great for gaming so if you do a lot of gaming that may be a good choice.

I've stuck with intel my whole life so I wouldn't be able to tell you how good the phenom II 1100T is

The 1100T is more or less a waste of money over a 1090T. They are effectively the same chip with the 1100 being 100 mhz faster. They overclock the same and that 100 stock mhz will make no difference. If you're going to buy a phenom II x6 def stick with the 1090t over the 1100t because it isnt worth the money for the 1100t.

@Fatality, thanks for the reply. I understand that its great, but will it bridge the gap between a 6790 and a 6870?

@Skuloth, only 1100T available :S.

Another concern is the mobo, if I go AMD, I can get one of these three mobos:

1) ASUS M4A87TD EVO AMD 870 Chipset

2) ASUS M5A78L-M AMD 760G

3) Asus M4A88TD-M EVO/USB3 AMD 880G Chipset

Third one is best, but a few newegg reviewers state that instability occur after a few months (overall rating is 4 stars tho?)

The intel mobos (Z68) available here are higher quality.

@ShadowBoss, I suppose, thanks . I just dont know about the mobos,

No I don't think it would bridge the gap. AMD (2nd option) with the 6870 is probably the better of the 2

My analysis
1) HD6870 will perform about 33% faster than a HD6790.
See the chart below. Even though it is for 1280x1024, it is close enough to reflect your resolution of 1440x900.
33% is a very substantial advantage. See chart 1 below.

2) Do not underestimate Phenom II X6 1100T.
While it might not be as attractive as a Sandy Bridge, it is by no means a slow processor. At stock speed, it can take two GTX570s at full potential.

Conclusion
Go for AMD Phenom II 1100T + AMD Radeon 6870


Edit 1:
For Metro 2033 with DX11 + Very High Details,
HD6790 gives 19.2 fps vs HD6870's 22.2fps. See chart 2 below.
Obviously both are not playable and you will have to drop down the settings.

go with 2 coz he has better graphic card and when you are using high res like 1680x1050 1920x1080 1920x1200 there are no cpu "FPS DIFFERENCE"..
go with 1100T + HD6870 ^^

For the mobo, at least my M4A87TD EVO has worked flawlessly in every way.
