I've got around 500$ to spend on a GPU and I've been trying to decide and I was wondering which you all would recommend for the best price/performance for 500$.
(It can be either Nvidia or ATI. IT DOESN'T MATTER.)
Offtopic question, What does the Interface do on a HDD, is the SATA 6.0 gb/s better than 3.0 gb/s in terms of perfomance? (I know thats the speed of the transfer rate but is there any technological means behind it? And if you could, explain the specs on HDDs and what specs to look for?)
Now, my analysis may be off because I have never used either of these cards, and I have never used Raedon, either. But, I'll do it anyway. (Please correct me (politely) if I'm wrong.)
1)The Raedon 6950 has 2 DVI ports, 2 mini-display ports, and 1 HDMI connector. It supports up to 4 monitors. Its core clock is at 810 MHz and the memory clock is at 5000MHz. It supports DirectX 11 and OpenGL 4.0. Cost: $289.99 (not counting rebate. W/rebate, it's $269.99)
2)The nVidia GTX 560Ti has 2 Dual-link DVi ports and a mini-HDMI connector. It supports up to 2 monitors. It's core clock is at 870MHz and the memory clock is at 4080MHz. It supports DirectX 11, OpenCL, DirectCompute 5.0, and OpenGL 4.1 . Cost: $279.99
Card 1 supports more monitors, and its memory clock is faster than that of card 2. Card 2 supports more recent version of OpenGL. Card 2 has a faster core clock and supports more technologies than card 1, but it's older than card 1.
As I said before, it depends on what you want. If you want a fast memory clack and want to use 3-4 monitors, then Card 1 might be your choice. If you only want to use 2 monitors and want a slightly faster core clock, then you might want Card 2 (which is cheaper, but only by $10.)
Again, I may be terribly wrong.
Ehh, I'm sure you could overclock them to run at about the same core clock in the end, but core clock speed isn't everything. Generally, the 6950s tend to beat out the 560TIs and are usually cheaper. On the other hand, what I personally view as the flagship of the 6950 line is the Sapphire 2GB Dirt 3 edition. It has dual bios and runs like a 6970 at the flick of a switch, and even then you can do some overclocking with it.
Overall, I doubt you'll be disappointed with the 560TI or the 6950, but definitely look into the Sapphire cards. They've got awesome reviews and they're fast.
The Meaning of Life, the Universe, and Everything.
It's my understanding too that both ATI and Nvidia will be releasing their next generation cards early next year. I have no idea if this is true or not, but I've also heard they will out preform anything available right now at similar prices. I haven't done hardly any research on them yet since I don't even have an adequate PC right now so I could be entirely wrong (this information comes from what I've heard on another forum.)
Personally, if I had your budget, I would look into it better information than I can give and potentially wait until January-March for the new cards.
