CF is for the birds.
Do you really need more performance, or are you affected by the techforum sickness?
Are you at 1200p or less? I can't find anything to make me switch over to my main rig right now, pretty lame considering one system cost me less than $500 while the other was almost $1800 and there is really no reason for it.
What game(s) are you playing that you feel are adversely affected by fps at this point?
I'm at 1080p for now. I will be getting a catleap in a month or two.
I find it's just the Crysis games that really bog me down. I don't really need the performance. I just figure it's a no brainer considering the bitcoins. Other games would benefit as well though as I find I can't really run much AA with most current games on my 7850.
I can get a 7850 for around $200 or else a 7950 for around $280. I'm doing this for better gaming performance and for the bitcoins.
I'm leaning toward the 7850 because it will give me a good crossfire configuration. I'm wondering though if I could just run the 7950 with my 7850 in "frankenfire" for even better performance.
The 7950 is a better deal in terms of bitcoins and performance per dollar as far as I can tell.
How much can you sell your current HD 7850 for?
i'd be inclined to sell it and get a 7970. Why settle for a 7950?
i would absolutely not run a 7950 with a 7850. Nor would i consider Bitcoins as any kind of money-making machine and leave that out of the equation (except with talking with the missus about it).
I could probably get maybe $180 for my 7850. The thing is though it's earning me $13/week in bitcoins. That means that if I keep it for 14 weeks or so it will earn me that much, minus my electricity costs.
What I think I'm going to do is get the 7970 once I can get a deal on one. They've been going for around $360 with 4 games when they're on sale. Then, down the line, I will get a tri-sli motherboard and add another 7970 and keep my 7850 in the 3rd slot to continue generating bitcoins. At that point I will be generating around 1500mhash/sec which will probably earn me around $80/week in bitcoins.
The tri-sli motherboards are surprisingly cheap. They're around $130.
