Choosing Gamign Computer [CPU vs GPU]

[GulleG]

Hey!

I have been looking for a new gaming computer for quite af while, and i have found two, who cost about the same.
My problem is, that i do not know which one to choose :/
I am really aiming for the best gaming experience.

Comp 1:

Specifications:
Cabinet: Cooler Master Elite 430 Midi Tower Black Blæser: 1x 120mm Front, Blue LEDs, mATX, ATX, 2x USB, 1x Audio
Power: Corsair CX 500W PSU ATX 12V V2.3, Standard. 2x 6+2pin PCIe, 5x SATA, 120mm Blæser
MotherBoard: Gigabyte GA-870A-UD3, Socket-AM3 ATX, AMD870+SB750, DDR3, 2xPCIe(2.0)x16, SATA 6Gb/s, USB 3.0
CPU: AMD Athlon II X4 640 Quad Core, 3.0Ghz, AM3, 2MB, 95W, Boxed
RAM: Kingston ValueR. DDR3 1333MHz 8GB, CL9 Kit w/2x ValueRAM 4GB DDR3
HDD: Samsung SpinPoint F3 1TB 7200RPM, SATA 3.0 Gbps, 3,5", 32MB Cache, 8.9ms
CD/DVD: Blu-Ray Sony Optiarc DVD±RW burner AD-5260S DVDRW 24x, DL, SATA, Bulk, Black
GPU: Gainward GeForce GTX 560Ti 1GB PhysX PCI-Express 2.0, GDDR5, 2xDVI, HDMI, 822MHz


Comp 2:

CPU - AMD PHENOM II, 1090T x6 (6x3.2ghz) 8MB CACHE (AM3), BLACK EDITION
Motherboard - GIGABYTE 870A-UD3 (USB3, SATA3, CROSSFIRE)
GPU - HD6850 1GB DDR5 GraphicCard T (XFX, BLACK EDITION), m. HDMI, DVI
Random - USB 3.0, SATA3 (600), ESATA, FIREWIRE, GIGABIT LAN OSV...
HDD - 500GB, 7200RPM (WD) (+149KR FOR 1000GB)
RAM - 4GB DDR3 1600MHZ HYPER-X KINGSTON RAM "DUAL CHANNEL"
DVD/CD - 22x SATA +/- OG DVD-RAM DUALLAYER DVDBRÆNDER (LG)
Power - 650W GAMER, 17DB, ULTRA LowSound, HIGHEND
Cabinet - CABINET ECCO-CASE
CPUCooler - ORIGINAL TEMP-controlled AMD CPUCooler with COBBER HEATPIPES
- 10 USB PORTs (2 FRONT)
- 7.1 SURROUNDSOUND Soundcard

The main difference is, that Comp 1 has the best GPU, while Comp 2 has the best CPU.

Here is some comparison sites:

GPU: http://www.hwcompare.com/8891/geforce-gtx-560-ti-vs-radeon-hd-6850/

I do not know if CPU is better than GPU.
I am really in doubt. Please help me out!

P.S: The computer is mainly chosen for gaming!

Most games will benefit from the GPU advantage more than the CPU advantage.
Between those two systems I would choose #1.

The Athlon II X4 will do pretty well in gaming, i would take it in combination with the GTX 560 over the Phenom II X6 in combination with the 6850 especially if you plan to game at higher resolutions. The higher the resolution the more likely the GPU is to be the determining factor, and either of those CPUs can put out playable frame rates so the only thing that will be causing you a noticeable difference will be the graphics card and how high you can turn up the settings.

 

[GulleG]

So if you took both computers side by side and played a 1280*1024 res High Quality, the 1st computer would perform best?

 

[hunter315]

If you are only playing at 1280x1024 you are going to be running into a CPU bottleneck on both of them because that resolution isnt going to stress either of those GPUs too hard, even at higher settings. In that scenario the second one would put out better frame rates from the stronger CPU but unless you are tracking it with FRAPS you wouldnt be able to tell the difference, at 1920x1200 the first system would do better than the second one and it would actually be noticeable.

Haha, well the only reason i said 1280*1024 is, that i am used to be the owner of a Stone Age computer

With that comment in mind, i think i will go for the 1st computer.

Thank you very much for you help!
And thank you for such a rapid reply
