7970 makes more sense if gaming at 2560 x ______
Looks like it.
Go back in time and un-purchase the 590?
That's not going to improve his performance today though which seems like that's what he is after.
Don't forget when the OP is not gaming, he can use 2x HD7970s to Bitcoin mine.
Current rate of Bitcoins is >
$6.00. A single HD7970 @ 1150mhz makes about 680 Mhash using
GUI miner. All the OP would need is to download GUI Miner, grab
AMD SDK Stream 2.6 or later and create a
wallet address to deposit them into from the mining pool such as
BTC Guild or
Slush's Pool. It takes 5 min to make an account at BTC Guild to mine coins and another 10 min to install a wallet, GUI Miner and SDK Stream driver.
A single HD7970 @ 1150mhz will make 12.04 Bitcoins a month @ $6 = $72 (
Calculator). 2 of those is $144 a month. Using adjustment for electricity rate (
alternative calculator) of $0.15 per kWh and assuming 300W of power consumption per card (600W total), 2x 680 Mhash = 1360 Mhash, that's
$88 a month after expenses.
Even if the OP mines for 12 hours out of 24 when he is working / sleeping, that's $44 a month x 6 months = $264 in
Newegg or Amazon gift cards for his next upgrade. :thumbsup:
If the OP games for 6 hours a day and mines for 18 hours, that's $66 a month x 6 months = $396. So in 6 months from today, he'll have a "FREE" HD7970 from trading in and $400 for his next upgrade and 60-70% faster performance at 2560x1440. That's a no brainer.
