What is the ideal core clock speed for most video games?

[Brad P]

Hello,

I am currently looking in to buying a new Video Card for my PC, and currently looking at two cards which are:

- ASUS ENGTX560 DCII OC/2DI/1GD5 GeForce GTX 560 (Fermi) 1GB 256-bit GDDR5 PCI Express 2.0 x16 HDCP Ready SLI Support Video Card ($169.99)

or

- ASUS ENGTX560 TI DCII TOP/2DI/1GD5 GeForce GTX 560 Ti (Fermi) 1GB 256-bit GDDR5 PCI Express 2.0 x16 HDCP Ready SLI Support Video Card ($209.99)

Now, ive written down the specs of both cards comparing and contrasting them on a piece of paper, and in the end the differences between the 2 are as followed

First Card ($169.99):
Core Clock Speed - 850 MHz
Shader Clock Speed - 1700 MHz
CUDA Cores - 336

Second Card ($209.99):
Core Clock Speed - 900 MHz
Shader Clock Speed - 1800 MHz
CUDA Cores - 384

Now, everything between the cards are identical, but there is at least a $40 difference between the two cards, and I guess what my question is: Is it really worth the extra $40 to get the second card, and will there that much of a difference between the performance levels?

Why to get previous gen gpu.instead get gtx 660 or hd 7870.

The short answer is: you probably won't see much difference between the two cards, almost certainly not $40 worth of difference.
But as ashish so eloquently points out, you're better off going with a different card altogether. My vote would be the 7850.

there is more than clock speed differences:
the first one is a 560 (non TI) and has 336 cuda cores whereas the second one is a 560TI and has 384 cuda cores.

for ~$169 you're better off getting a 7850 and for ~$209 you're better off getting a GTX 660 (that also has 2Gb of memory).
