I had the time to read a few pages of comments / questions pertinent to overclocking Vega 56, seen a few people with the Pulse card. If you guys would give me a bit of leeway if I sound like a bit of a know it all, and be mindful I have spent days upon days overclocking and benchmarking mine I would be grateful...In my opinion the following a hard facts:
Happy to chat or help anyone further if I can.

- Don't bother flashing to a Vega 64, if you have Samsung HBM you may be able to overclock beyond circa 950GHz to circa 1000GHz. BUT the bios increases the voltage through the bios to allow furthering the HBM overclock, it adds heat to everything. You will lose an HDMI display port (I think?), your max core clock will probably reduce due to the extra temps and power usage etc. You might also break your GPU. Overclocked to 1600MHz core and 940 to 950MHz HBM with enough cooling to avoid throttling and you will be within circa 1% to 4% of a stock Vega 64. Vega 64's overclock poorly so even both overclocked a 64 might onlyclose the gap by a percent or 2.
- Anything beyond 1600Mhz core and 940MHz HBM, becomes nothing more than a *****ng contest. I have benchmarked my card up to 1720GHz core and 945MHz HBM, its error of margin results.
- The blower cards are useless and the expensive ASUS Strix cards are overkill and massively overpriced. Get the Pulse, mine was £200 quick from OC's, customer return with 3 months warranty.

Frame rate drops / stutters in game like you mentioned are only an issue with something of a lack of understanding pertinent to the architecture of old Sandy Bridge quad cores like mine. Dropping one or two settings from ultra / max etc applicable to physics settings in games makes a world of difference, and I can never see a difference visually. Don't forget my 2500K is overclocked to 4.9GHz so that puts it on a whole new level to a stock CPU. I have been considering buying a second hand 2600K or 2700K, the 3770K as your suggestion would however, and IMO be a waste of money. Second hand prices and stock settings the 3770K represents a circa 30% cost premium against a 2600K or 2700K , gaming performance is identical. Incorporating my custom water cooling loop, a 2500K, 2600K or 2700K would outperform any of the 3000' K CPU's. 2000'K's have a soldered heat spreader, big reason my 2500K overclocked to 4.9GHz. 3000'K's have a cheap “TIM”, they run way hotter and overclock much lower, 4.3GHz / 4.4GHz is about the best they do even on a custom water loop. Upgrading to a 2600k or 2700K might be my best choice, glad you said the same...BUT, if it does not overclock past say 4.5GHz it will actually be a downgrade in certain games. I usually demote my gaming PC's to my under staircase media sever, but my gaming system in question has a temperamental motherboard that beeps unknown error codes once or twice upon start up requiring the odd hard reset on the PSU switch. My media sever is set for wake on lan from the TV, laptops, phones etc. My gaming system would be no good. It will either be retired to the front room hidden in an alcove cupboard as an occasional gaming PC for entertaining drunk friends, or be thrown away. TBH I was like this with my Q6600 / ASUS Maximus Formula system, the 2500K was night and day upgrade tbh, I should just bite the bullet I think. The Q6600 is now my media sever underclocked and undervolted to 1.6GHz, 12 TB internal storage, with 12 TB USB 3 external backup.
