I am in the market to upgrade my graphics card and have narrowed it down to the Sapphire Radeon HD7750 HDMI 2GB or the Gigabyte GeForce GT 640 OC Dual-DVI HDMI 2GB

Questions

I'm pretty sure i'll have to upgrade my PSU so how many watt should I go for ?

With a new PSU will my system handle either card

which one should i go for?

Cheers in advance

A good 400W-500W PSU should do the trick for either cards. Buy from these brands: Corsair, XFX, Seasonic because bad quality PSUs can destroy your system. Also, what purpose are you using this graphics card? On low-end cards like these, a 1GB and a 2GB model make almost no difference unless with ultra high resolution/visual effects (AA, etc). Try to get a 1GB model of a better card such as a 7770/GTX 650. If I had to I would go with the 7750.

Hello there, try get something like 7850 if you wanna go for mid gaming or high gaming.
You also can take the 7750 but i would suggest 7770 would be better .

 

[fanboynz]

I'm using it primarily for gaming and mainly for Star Wars Old Republic

what resolution will u be playing at

 

[akshayghai29785]

take a 7790 all the best with gaming & also as asked what resolution you would playing on

 

[Matsushima]

what resolution will u be playing at

Presumably, 1600x900.

By the way, have you considered 1GB models of the 7770, 7790 and 7850? You really don't need to pay more for a 2GB version.

I've narrowed it down to the following cards given my budget !money is NZ dollars where im from)

Palit GeForce GTX 650 HDMI 1GB for $155

Gigabyte Radeon HD7770 OC HDMI Dual-DisplayPort 1GB $165

HIS Radeon HD7770 iCooler HDMI Dual-DisplayPort 1GB $165

Gigabyte Radeon HD7770 OC HDMI Dual-DisplayPort 1GB $172

Which of these would be the most suited to playing the likes of old republic on mid- high settings with smooth gameplay?

7770 is alittle faster.

pick the cheapest 7770 they are better than gtx 650

 

[Matsushima]

Get the 7770, it is better than the GTX 650. I would probably get a Gigabyte, but also see if you can get a 7790. A 7770 requires a 500 watt power supply, but a good 450 watt probably can handle it. Remember, the 7770 requires an additional 6-pin PCIe power connector.

 

[Xavier Tan Sync]

Sorry for late reply and take the Gigabyte Radeon HD7770 OC HDMI Dual-DisplayPort 1GB $172
It runs your game smoothly

 

[Matsushima]

The models do not make much difference, the actual processors are the same, 7770 is still 7770 and you will not see a huge performance boost from the overclock.
