Hello, I was considering the following graphics cards:
Sapphire Radeon HD 5750
VTX3d Radeon HD 5670 x2(crossfire)
VTX3d Radeon HD 5770

This is my system's specs:
MSI k9a2 Platinum
AMD Phenom 9950 Black Edition
MSI Radeon HD 3870
4gb ddr2 ram
Gigabyte 700watt power supply

I'm mainly going for a direct x11 card because according to the charts I saw in here the framerates are considerably higher on dx11 compared to the same system on dx10

my questions:

1. Which card(s) is better?
2. Is it true that vtx3d isn't a good brand and it overheats? It caught my attention because of the good prices and I'm not looking for a higher end card.
3.Is it true that my system can't run the cards in the list at full capacity?
4. Is it possible to crossfire either one of thoes cards with the one I already have?
5. Do I need a stronger power supply to crossfire?

Thanks alot in advance

1. Which card(s) is better?
Out of those I would say the single 5770.

2. Is it true that vtx3d isn't a good brand and it overheats? It caught my attention because of the good prices and I'm not looking for a higher end card.
I never heard of them, however I imagine they use the stock reference cooler in which case overheating shoudlnt be a problem, you should be more concerned about the warranty.

3.Is it true that my system can't run the cards in the list at full capacity?
Your system can run that at full capacity.

4. Is it possible to crossfire either one of thoes cards with the one I already have?
That is impossible, two different generations of cards.

5. Do I need a stronger power supply to crossfire?
No 700watt PSU is more than you need.

1. A single HD5770 is your best choice of those options.
2. I am not familiar with that brand. For ATi cards, I would buy HIS, Sapphire, or XFX if buying based on familiarity.
3. Your system has PCIE x16 2.0 slots. Your CPU is not strong by current standards, but will not significantly bottleneck these cards.
4. No. Crossfire requires two cards of the same model. Manufacturer can be different.
5. Your PSU is more that enough for any of these cards, or even a pair of them.

Thanks for all the info everyone. I'm either going for an xfx 5770 from ebay or the vtx3d 5770 from a local shop

I'd buy locally long before buying from eBay, unless I were particularly confident in the seller.
