ECC memory can play games, yes - you add a little latency for error correcting but, fundamentally, there's very little difference between ECC and non-ECC.
Where it likely will be a problem though is ECC memory (very) rarely work in 'consumer' motherboards, which do not (generally) support ECC memory.
