The time has come to upgrade my graphics card so I am looking for something around the £200 - £300, closer to the lower end of my budget the better. I use my computer primarily for gaming, crysis, bad company 2 etc.
I am debating whether to go for a single 5850, most likely the sapphire Toxic 1gb or two HD 5770s in crossfire or just spend the whole budget on a 5870
I am leaning towards the 5850 I have linked to atm, one of the reasons being I don't think my 550w psu will cope with two 5770s?
I have never bought componants from amazon before but that is the cheapest I have found that particular card so far. I would normaly buy from ebuyer or scan.
My current specs are:
Intel Q6600 2.4GHz
4GB Corsair XMS2 DDR2 800MHz
VX550W Corsair PSU
Asus P5Q Pro motherboard
Windows 7 64bit
Monitor Res: 1920 x 1080
hmmm...an hd 5870 will be good on that 550 watt psu and will be good for your...
but i were you i will rather get an gtx 460 and overclock it and it will perform better than an hd 5870..
and by the way if your budget is £200 - £300 then hd 5860 will be good for you but if it's $ then hd 5870 is out of your reach.
In a few benchmarks it is better than hd 5870 but mostly it will be equal or a little lower than hd 5870...but gtx 460 is mine choice and it will be ideal if there is an possible psu upgrade it will help connecting 2 gtx 460 in sli later and will be a greater boost...
With that budget and no SLI your two options should be either the HD5850 or GTX 470. I would probably go for the GTX 470 as it is a better card and the price difference is so close.
If you do go for the HD5850 I recommend the Asus DirectCU card if you are going to overclock(you should.) Most of the custom HD5850s(like the Vapor-X) have dropped voltage control which will limit you to an OC in the 850-900mhz rather than the 1ghz+ the card can usually a achieve.
Go with the 5850 toxic, as long as it fits in your case . Your PSU will handle it just fine. Yes two 5770s would generally be faster than a single 5850 but it gives you room to add another 5850 latter when you need it where as if you went with two 5770s next time you need a GPU boost you would replace both of them .
I would also recommend overclocking your CPU to at least 3.0Ghz. With a 5850 you may find that at stock speeds your CPU may be your limiting factor, depending on your settings.
I didn't read the whole thread, but I have a 5770, and I am basically maxed out (except for AA and AS?[not sure if that is the correct name of the one in there... lol] they are at 6x out of the next setting 16x) no lag except for explosions in my face... lol. You only need a 5830 or so to run well... (not sure on crysis, nerver played it...)
