I was originally going to get a 7970 with an i7 3770k but I saw that the GTX 780's came out a couple days ago and I would LOVE to get one seeing the benchmarks on it. But a 780 with an i7 would kind of blow my sub $1500 budget and I would be missing out on the 4 free games from the 7970. Would an i5 work well with the GTX 780? I want to make my rig at least future proof for gaming for the next 2-3 years, thats why i wanted to get a 780. Thoughts?
