LOL, thanks for singling me out! Lots of people here that can help you better than I could.
That being said...
I am fatiguing early and not getting a full work load done with chest. My chest is the one thing lacking on me, and I try to hit it with a variety of angles and exercises from ones listed here and in mags.
I take it you dedicate an entire day to blasting the chest from every angle? That's your problem right there. First of all, you're doing too much. For some people, volume works superb..But it doesn't sound like you're one of them. (don't worry, it's a small group) Neither muscle fatigue nor being sore is going to determine whether or not you're going to grow. Another point to make is that most "muscle mags" workouts comes from editors that are a buck-twenty soaking wet with a pair of 10" pythons for arms.
So, I ask you, what do you do when you want to get better at something??..The answer is to practice more at it, or in your case, increase the frequency while at the same time decreasing the overall volume.
Second, the amount of volume and the high number of reps is of course going to fatigue your triceps and anterior deltiods before your pecs. That's why I'm a proponent of at least splitting the workload between two days vs. trying to do it in a single session, once a week. Cable crossovers aren't an exercise you should be doing anyways, unless it's high reps with very slow tempo to increase time under tension..Like as in a superset with a compound.
Try dividing that total volume between two days instead of just one. By doing half of what you're used to, you'll be able to focus more intensity into those lifts. I'll tell you, when I first started, my program looked sorta similiar to what you're doing, and about halfway through, I was basically just going through the motions....Less is more.
How many days are you going to the gym? There's a lot of different splits out there that are better than "once every 7 days"..
This is of an upper/lower split. You're basically taking whatever you do per muscle in a single day, and divide it between two workouts. I'll use chest as an example..
Monday: Upper body (chest: 3 x 5-10 flat barbell, 2 x 10 incline dumbbell)
Tuesday: Lower body
Thursday: Upper (this time do 3 x 5-10 incline barbell, 2 x 10-12 flat or decline dumbbell)
Here's another one that only has 2 days off per week vs. 3.
So, I'd recommend splitting up your current assault on your chest from one day to two days and go from there.
