I'm looking to pick one up. NCIX has them for $319 until dec 31. I have a midsized case and I run an I5 2500K running at 4.6GHZ. It looks like this little card limits overclocking as it probably can't handle the heat. Video card overclocking isn't something I couldn't care about anyway. especially for FSX. Does this card run the same as any other GTX 970? Or am I better off going after an ASUS strix or the G1? If it runs the same as any other 970, why spend the extra 100. plus it uses less power. Any input would be great because i'm looking to purchase before the 31st. thank you
