Hello everyone, last week i bought a msi gtx 780 3gb OC twin frozr for 450€, i did hear about 970 coming around, but today, i was surprised when i saw at the same website i bought my card , the msi gtx 970 4gb OC twin frozr model for.... 349€!

I'm still in time to send back the 780 for a refund and buy the 970... So my questions are :

1 - Shall i do this? Or keep my 780?
2 - Is the 970 more powerful than the 780? If so , i will get a stronger card and 100€ back

I don't really know what to do about this , what would you guys do? Thanks!
