I'm looking at GTX460 1 GB from nVidia and HD6850 from ATI.
I don't really care which card is better overall or in general terms. I need it for one purpose: 1920*1080 resolution and OCed to the max achievable before the card dies or my ears kill me.
Games I envision myself playing (where it matters) include Starcraft 2, Fallout 3 with all the addons, Fallout: New Vegas. If this matters any, I play RTS, which can mean huge performance drops when you produce a lot of units. If something in one card (GPU architecture, memory sticks, whatever) can reduce this factor better than the other card, I'm all for it.
Where I live, the price is 599 PLN for the nVidia and 699 PLN for the ATI (0.85 ratio). The 768M version costs 529 PLN but I don't trust <1GB for 1920*1080.
Also, if you believe there's any reason to buy some older tech (e.g. HD 4870x2, GF GTX265 etc.) or the price to performance ratio justifies buying a higher new model (e.g. GTX470, HD 6870), shoot away. (Also if you're selling one.)
I know it's Christmas time but I'm not gonna wait a month for an uncertain $10 price drop.
What I have now is a HD4850 Radeon, which needs replacing for additional reasons (stability issues), so even though HD 5770 or 4830 or GF GTS450 may offer a better price to performance ratio than newer/higher models, I want to feel the difference and keep up with the times.
Theoretically, I could probably get away with buying two Radeons and putting them in Crossfire. My PSU is rated 520W but it's quality stuff. I have a P45 mobo, a C2D 7200 CPU, two DDR2 sticks, one HD, one DVD-RW, one PCI-E soundcard, 1 case fan, 2 CPU fans, not much on USB (keyboard(s), mouse, the rest has its own power plugs). So if there is some low voltage Radeon model where I can buy two cards and it will beat the price to performance ratio of a single newer card, I'm willing to look into it. Especially if getting 2 GB RAM total this way would help me in a higher resolution.
Thanks, guys.
