Could I power a GTS450 or HD 5770 no problem with room for ram update?
Additional RAM beyond 4GB will not boost your gaming experience.
Yea I know that but I am planning on throwing another 2 sticks to get 8gb of ram, and would I be able to power the rig with the 500 watt earthwatts running a 5770 or a GTS450?
5670 would be able to max out Black Ops and Portal 2 but not BFBC2 and Crysis 2. I suggest getting a 5770.But even still you can probably only play BFBC2 on medium settings at 1080p.The 5770 is better than the GTS450.
I am pushing at least a 5770 because of the resolution you have.
I am too suggesting the 5770 for the resoultion.You won't be able to play acceptable fram rates with anything less.And the 5770 is just the best bang for your buck.
The MSI version i suggest has free Shipping.The Vapor X version has a $20 Mail in Rebate which after the shipping leaves the price tag still at $120.MSI version you dont even have to deal with the mail in rebate.Although it's a good card i don't see the point in getting the Vapor X if it's just going to end up being the same price and you have to go trough the trouble of a Mail in Rebate for just $20.
Also again will I have room for Ram upgrades or am I running borderline with the 5770?
Canada newegg links are broken.Is it the XFX 4850? Get the 4850 if you can't afford the 5770.But the 5770 is a slighty better/newer card.If you can manage,get the 5770 over the 4850.The 4850 is better than the 5670 but the 5770 is better than the 4850.
