I can here's a different question should I do 2 680's or one 690

close to same price the 690 is as followsMemory Type
GDDR5
Video Memory 4096MB
Core Clock 915MHz
Memory Clock 6008 MHz
Memory Bandwidth 384.52GB/sec.
Stream Processors 3072
Memory Interface 512-bit

the 670 is as follows
Memory Type GDDR5
Video Memory 2048MB
Core Clock 1084 MHz
Memory Clock 6208 MHz
Memory Bandwidth 198.66GB/sec.
Stream Processors 1536
Memory Interface 256-bit
trying to figure out the best way to go
