PSU: "2x PCI Express 6 pinů"

This will only allow for one Graphics card. I made the same mistake on my rig, starting with a HD 5870 and planning to expand, because I thought "oh, I have 2 PCIe power connectors, that would suffice for two cards". Nope, one card needs two connectors already!

Also, I would not buy that much RAM from the start. You can surely save some Korunas when you buy one slower 1 GB bar. Apart from that, it doesn't look too bad, but it will probably take 6-12 months to pay it off completely. Although if you only plan on recuperating the cost of the GPU (that's the 200 USD, I guess) it will be quicker.

Thanks for the feedback. I am still trying to get my head around all the mining info. I posted my first comment after doing a lot of reading and researching. Then, this morning, I did some more reading and turned some of my conclusions on their heads. Ugh. Actually, the 200USD refers to the CPU, Mobo and RAM. I wanted them to be low cost and energy efficient for mining. Don't we all? The GPU can be a toy for later if I stop mining. Even though, I am just dabbling right now, I also want the GPU to be the best bang for my buck in case I decide to take it further.

To reply to both you and Being, yes, I am hoping to recuperate my costs after about a year. I would love to find a way to do it sooner.

It's been hard finding the sweet spot of high Mhash/s/W with a reasonable investment amount. There are so many variables. I think I find a GPU I like, then other hardware is more expensive or unavailable. And why don't most people write their results in Mhash/s/W? Who really cares if they are getting 2Ghash/s if its costing them 1Mwatt in electricity?

EDIT: Also, I wanted to get opinions on the GPU I listed in my earlier post. ASUS MATRIX 5870/2DIS/2GD5

This looks quite a bit different and definitely more expensive than other 5870s I've seen on this forum. For example: XFX ATI Radeon HD 5850 1 GB DDR5 2DVI/HDMI/DisplayPort PCI-Express Video Card HD585XZAFC

I haven't been able to find any mining results on the ASUS card. Any opinions here?
