Is this HD 7770 ok?

It's ok, but i recommend to you VAPOR-X. It costs a little bit higher. Or Gigabyte 7770 OC which is cost same as Sapphire. Why VAPOR-X? Because it has higher clocks and core additionaly can be overclocked for 10%.
 



Case : Vantage Blue Gaming Case
Motherboard : Gigabyte H61 USB 3 Motherboard Technology
CPU : Intel Core I3 3220 3.3ghz CPU
Memory : 4gb DDR3 1333mhz Memory
Power Supply : 450 watt

Thankyou
 
I don't have any preference. I currently just have a 7 year old monitor. Will be getting a
19" HD monitor. So Just the highest settings i can get im guessing.

 
Yep, Sapphire is ok. Gigabyte is a little bit better, in my country there is almost no difference in price within Sapphire and Gigabyte, don't know how in your's.
 
The gigabyte doesnt have crossfire?. Is this going ti be much of an issue. I wouldve thought the more expensive of the range who have this feature
