GPU SLI Compatibility

I know this is a stupid question but I haven't experience this yet.

 

Do I need to match the clockspeeds of different GPU brands when i'll SLI? I'm planning to get a Palit Jetsream then a Gigabyte G1 Gaming as an upgrade in the future. Both are GTX 970s.

My Current PC Codename: Scrapper

One of them will slow down to the speed of the slowest card but nothing bad will happen

RIG: I7-4790k @ 4.5GHz | MSI Z97S SLI Plus | 12GB Geil Dragon RAM 1333MHz | Gigabyte G1 Gaming GTX 970 (1550MHz core/7800MHz memory) @ +18mV(Maxed out at 1650/7800 so far) | Corsair RM750 | Samsung 840 EVO 120GB, 1TB Seagate Barracuda | Fractal Design Arc Midi R2 (Closed) | Sound Blaster Z                                                                                                                        Getting: Noctua NH-D15 | Possible 250GB Samsung 850 Evo                                                                                        Need a console killer that actually shits on every console? Here you go (No MIR/Promo)

This is why you should not get an FX CPU for ANY scenario other than rendering on a budget http://linustechtips.com/main/topic/286142-fx-8350-r9-290-psu-requirements/?p=3892901 | http://linustechtips.com/main/topic/266481-an-issue-with-people-bashing-the-fx-cpus/?p=3620861

I think they automatically sync to each other

Specs: CPU: AMD FX 6300 Motherboard: Gigabyte 970A DS3P RAM: HyperX Fury 16GB 1866MHz GPU: MSI R9 270 OC edition Case: Sharkoon VS3-S SSD: Samsung 840 EVO 120GB HDD: 1TB Caviar Blue PSU: Corsair CX500W

No you can use any 970s the faster one will just run at the speed of the slowest card

It's ok for the clockspeed to vary so long as it's not excessive, in most overclocking utilities there's a sync button that will sync the cards to the slowest card.

One last thing guys, do you think If I get two GTX 970 AMP OMEGA instead and put it in my Bitfenix Ronin case with a Gigabyte Gaming 7 it will be too tight that' they'll practically be starved of airflow?

No, not really if you have even decent fans.
