So I've been looking for awhile now and even though my card is "outdated" its still holding up to what I use it for. I've been looking for a waterblock for it and happen to run across the Alphacool NexXxoS GPX - ATI R9 270 M06. Now the dumb question I have is since I haven't ever watercooled a vga would this work for a 2gb version of the card not the 4gb version. Yes I realize it's not the brightest question probably just outright dumb but I have looked at a 4gb model and it doesn't look externally any different. Is there any difference on the internal if anyone knows.
