PC System Requirements speculation

Dragon Age Inquisition on High and Ultra on a Gtx 745? You must be running at low frames then, probably under 30 frames per second. The target for PC gaming is usually 60 frames per second.

Replacing the graphics card is a very easy process, it will hardly take a minute. However, as Pearl mentioned above, you will also need to replace your Power Supply Unit - you will need more power to run a more potent graphics card. Replacing the Power Supply is significantly more complicated, there are lots of different cables involved, each one providing power to a different component, as well as the need to do some cable management afterwards in order to get leave room for air flow inside the case. Every slot is keyed and everything is standardized, nevertheless, you will need to have a basic idea of each individual PC component and where they are inside your case.
Well, replacing the Power Supply is frankly not that easy. It is one the core components of the PC.

Also, if you have a "compact gaming PC", that means you might have a pretty compact case, one that does not have enough room for modern full size video cards.

Despite these adversities, I would strongly suggest replacing your card (and with it your power supply) for a more modern and potent one, even if you need to get help from a friend or pay someone to get it done. You have an extremely powerful and expensive processor, a huge surplus of memory ram and a graphics card that is a severe bottleneck when it comes to gaming.

Thanks for the advice It's something to think about. I cannot express how pissed off I was when I realized they'd lied to me about the graphics card. At that point I was just so done with them though.

I asked the IT guy at work if he'd consider helping me, but he said he couldn't because it would violate some kind of work rule. I have a cousin who is in IT but I am not overly fond of him, so lol ... we'll have to see. My dad might be able to help me. He was a big computer guy at the plant he worked at but his knowledge is probably very dated.

I'll have to see. For now the plan is to just see how the game plays and probably upgrade in the summer.

Ehhh what's that mean guys? Yes it is a brick... are... are they not... are they not all like that? It has been a looooooong time since I've had a tower. Now that I think about it... it did not have a brick. But yes the alienware has a brick.

Mine is 330w I guess they made it external for space and heat issues.

This pains me on a metaphysical level.

In that case, scratch everything both SpaceVegan and I said about power supplies. Just worry about getting a small-form factor/low profile graphics card. Double-check the manufacturer specs to make sure it doesn't need more than 330w of power, and you should be good to go. The GTX 1050 Ti is an excellent choice with this restriction in mind.

I kept seeing this... do it yourself, build it yourself! You might as well tell me to build my own car. It can be hard to understand that not everyone has your level of knowledge. I'm a teacher, so believe me, I encounter that all the time lol "Why don't they GET this? Isn't it so easy? Isn't it OBVIOUS?" But it isn't. And when you have no one to assist you or guide you, your only option IS to buy a pre-built one. 

Pearl It's not a BIG, big deal; I am pretty happy with how all the games I play look, so /shrug. This is also how I watch TV (Netflix, YouTube, etc.) since I don't have cable. It has to be compact-sized. There are pluses and minuses I guess! I'm not a huge geek when it comes to graphics and stuff; if it looks nice and moves smoothly I'm happy. I just was worried it would look REALLY bad on ME:A and was despairing having to upgrade.

I recently replaced my ram, gpu and psu which was the first time doing anything with the insides of my pc. Worked out fine, mostly (I accidentally plugged out the cd tray and it doesn't work anymore, it was stuck before so it's not a huge loss), it really is relatively simple and I'm the least technically inclined person ever. Now my processor is lagging behind the other bits because a) it's pretty expensive and it seemed more complicated than replacing the other stuff and I didn't wanna risk it.

Also, ever since I switched the parts I've had an extra terabyte hard drive on my computer that I can store stuff on and everything despite the fact that I only have two hard drives in my box. Where does the extra one come from? I don't know. But I'm guessing hardware fairies.

i5-4460 3.20GHz.
