I like both but lean toward MSI.
Run away from Sapphire in Portugal. Costumer support is worse than Asus', seriously, go Asus. Sapphire is a good brand, but if you ever have a problem, god help you.
As for having it in stock, have you considered ordering online? A quick search finds me a MSI 270 at 167€. That's a nice price.
Don't care, I've got 3 years of warranty on that deal in a local store, should it go kaput sooner, will get an equal or faster card as a replacement.the problem is that the ASUS 270 does not have any type of ventilation for the memories VRAM, and they reach high temperatures (above 85C). Now a plate to warm both will not last long, I think
If all you do is gaming, then GTX 660 should be a better choice, imo. Because well, it has PhysX (in some games it's a must, imo) and things like Adaptive Vsync (which I really like), out of the box. And if the price is really hot, it's a no brainer 😎I can buy an ASUS GTX660 OC used for a lower price, ya recomendamk me? or better go to R9 270?
