Hello I am considering upgrading my lone HD 4830. My system is as follows:
Intel E7400
DFI LanParty - LT (DDR2 version)
Corsair Dominator 1066MHz
Antec Earthwatts 500W
HIS Radeon HD 4830 512MB
500GB Seagate 7200.12
Zalman CNPS9500
Thermaltake Armor MX+
21.5" LG Flatron 1920x1080
I was going to build a new i7 920 system but that has been halted as I cannot justify the cost at the moment. So instead I am going to put a little money into my current build. As well a a graphics card I shall be getting a new 1TB HDD and maybe a new cooler.
From what I understand 4830 x2 > 5770. Note that I am in Australia so prices are different. I can get a new HD 5770 for $185 or I can get a used 4850 1GB for like $70/$80. I know that the 4850 will be limited to the speed of the 4830, right?, but will the full 1GB of RAM on the 4850 be able to be used? Also would there be any performance increase if I got a HD 4870 1GB instead of the 4850? they go for about $100 used.
I was also wondering if my E7400 at stock speeds will bottleneck two 4830s, I am happy to run at 3.8GHz on my current cooler but 4.0GHz requires a lot more voltage and the temperature reaches 65'C on load which I'm not that happy with. Would 3.8GHz eliminate a bottleneck?
For the performance boost of an extra 4830 compared to the low cost, I'm guessing this is the best option though I am not to knowledgeable on crossfire systems. I know that they are considered worse then an equivalent single card system, but a 5770 is a lot more expensive.
Thanks for the help.
