Crossfire 6970's?

[satanicguardian]

Hi guys,

I've got a fairly old rig now (completely skint!) and I'm tempted to crossfire the existing card, specs below:

Phenom II x6 1055T @ 4.2ghz - Asus RoG 890FX - 8GB XMS3 - HIS Radeon 6970 2GB - Samsung 840 Pro 128gb - XFX Modular 750W

Would I notice a decent performance leap moving from a single to a crossfire setup? Never tried one before, the card by itself is powerful and will run assassin's creed unity at 30fps on Good settings, but I want a bit more oomph.

Bang for buck would I be better investing in a new card totally or would crossfired 6970's be pretty strong?

Also would my XFX 750 support 2 of these cards?

Cheers!

Jamie

I went from a single 6950 (with unlocked shaders so basically a 6970) and managed to pick up a second for £45 from a certain well know auction site and the difference is definitely noticable. Benchmarks have all improved with very good scaling and games I can now turn up the AA and settings more. I'm using a basic 700w psu and it's been fine for mine.

So you'd recommend giving it a shot?

Mine is a HIS radeon 6970, does the manufacturer matter? It's tricky to find an exact copy of the same card of that age

Yeah if you can pick one up cheap I'd say it's worth a go. Mixing brands isn't a problem, mine are a Sapphire Toxic 6950 with unlocked shaders and a standard MSI 6950. Both running at different clocks and they work fine. Also worth noting that you can crossfire a 6950 with a 6970 which may increase your options of finding one cheap while still being a decent upgrade.

Sweet, I'll have a shot at it!
