Hey guys,
I have an OCZ GameXstream 600 watt power supply and was wondering if it could handle a single 4870 with the current configuration. Also, how much of a difference do you think a 4870 would make over my 8800gt?

Hello and welcome to the forums mate :)
OCZ GAMEXSTREAM 600W is a solid PSU and will handle that HD 4870 well :)

I'm going to tag onto this thread, as I have a 600W Enermax PSU (http://www.aone.co.uk/ProdInfo.ASP?ProductID=222) and want to know pretty much the same thing. Difference is my PSU only has 2 12V rails

I'll be purchasing or already have:

GO stepped Q6600, giving it a modest OC
2gb Crucial Ballistix 1066
Ati HD 4870
Asus P5E X38 Motherboard
3 SATA 7200rpm HDDs
2 DVD/Blu Ray Drives

If people think going for a dual core E8XXX is a better option for now, then I'll happily drop down a bit to save wattage.
I've been onto Thermaltakes Power check site and feel like they've underestimated the 4870 somewhat, given the reviews I've looked at.

A high-end system uses about 300w on load. It's recommended to have a PSU that can deliver twice that: 600w. That way efficiency and noise levels are (most of the time) optimal.

So yes, I would say that your Enermax 600w PSU is adequate.

After some reading I'm starting to lean toward a 4850 crossfire setup. I know this would use more power than one 4870, but do you think it would still work?

Not sure about 4850 crossfire with the PSU, but I know it can power a 3870x2 (I had to buy a 6 pin to 8 pin adapter to overclock it though).

K, guys sorry for hijacking this thread, but the OP has 4 12v rails. Mine is a 450W but single 12V rail with 25A. What is the major difference here?? Will my 4850 work??

I guess I'm going to get 2 4850s and crossfire them. http://img.tomshardware.com/forum/uk/icones/message/icon7.gif
Hopefully my power supply can handle it..http://img.tomshardware.com/forum/uk/icones/message/icon4.gif.. if anyone thinks this won't work please tell me before I order them tonight.

Thanks
